Alkaline Batteries- avoid them at all cost.

For those of you with expensive portable equipment or even flashlight like Mag-lites. One of the worse things you can put into a device is an Alkaline battery. They are destructive and leak every time. They could be considered hazardous material the way they destroy electronics by their leaking and corrosive fluids. I am surprised that the EPA has not outlawed these terrible junk batteries and there are many better choices that will cost you less in the long run. I suggest you get Tenergy NMH or Nickel Metal Hydride batteries that may cost more initially but when you can use them 1000 times there is not a lot to figure out that they are worth a pile of money saved. I even have some AA cells from 2001 that still work. The important part though is that the DO NOT LEAK. Abandon the purchase of junk Alkaline batteries, save money and your equipment too. Head over to All-battery and buy the Tenergy product like I do and no more trouble. No I do not own or work at ALL-battery. I just have had very good luck buying their product and not one failure yet- 9V all the way to AAA and they have rechargeable 123A batteries too. Here is to make it easy for you-

Known GOOD Service Facilities

For a time there has been a lack of good service facilities for the repair of tape decks but in time some of them have come out of the woodwork to make themselves know. This is a list of the ones I know do good work.

Not everyone is perfect and I even get complaints due to wait time.  But on a whole these places  99% of the time will fix your unit well.

Need a Good SM avoid Hi Fi Engine

I have been working on units a log time and some of the time I get requests for help that I do not have manuals for so over to Hi Fi Engine I went. Most of the time  I was able to help the other guy for no cost. Well most recently I was working on a  Sony 854-4 where I got the manual from Hi Fi Engine. The schematic is so bad that you can not see what the part numbers are- what idiot scans stuff like this and what further idiot puts in on a site for some poor person to download and try to work with.

Well I made a comment to them about the poor quality and now I am done with their poor scans and idiotic behavior. Why don’t they come up to standards rather then kick people out from downloading their garbage.

No matter, I am not going there anymore and do not suggest to anyone that you do either. If I can not fix a product with all my experience and their blurry manuals what makes you think that a person just starting is going to be able to.

Get all you manuals in paper from Stereomanuals.com

This place will get you a good and clear product.  http://www.stereomanuals.com/index.htm

Hi FI Engine Quality-JUNK!

Anybody Want a Web Blog like this one? Look at this-

I keep on getting comments on how people want a blog like the one here that I put up. Well, it is not that hard to do and it is very affordable. This link here will get you to the trial one month evaluation. Actually for the quality of the product they deliver and at a terrific price it is a no-brainer.

I highly suggest that you look into this and not pay some SEO person hundreds of dollars to make you a different site. You found me didn’t you?

Items Ready to be Sold with 6 Mo. Warranty

These items listed  here are ready to be sold. Not every one will be a Mint as these are older units and often times rescued from adverse locations. Many of them are very acceptable and the pictures here are of the actual units. More units will come available as they are finished.

Pioneer CTF-700 $300.00  Shipping is extra. If interested or if you have questions, E mail skywavebe@sbcglobal.net

This unit was sold and I have not been good as listing things here as there is no time for it but there are other units to sell. I have two NAD 6300 units to be sold too. A few open reels decks too.

HINTs to Posting Comments-

I seem to get posts that are ridiculous as to subject matter. There are Viagra sales attempts, T shirts or Jerseys, Shoes, Health plans and diets and then the Porn stuff that is trashed immediately- even if it is in your user name.

This site is about tape deck repairs and if you can not figure that out I just told you. If you attach links or URL that go nowhere the post will be trashed. If you think that a URL to Chinese or other language that I can not hope to ever understand, that is trashed.

Why not save yourself a bunch of frivolous typing and stop wasting time.

It does not take me long to trash a post.

Today I trashed 86 posts- there are still a bunch of stupid people posting junk to the blog. They are all gone now: Jakarta Security if you business is that poor that you have to look for client here?

As soon as I see ZUNE the post goes. This is NOT about those devices.  WE are not selling Jerseys here either- they are immediately deleted.

There is a reason I do not type in Spanish, Russian, Chinese nor Klingon. I can not read it so it gets trashed.

 

 

Teac X7R and other X7 models Fast Wind Speed Fix Modification

One of the most aggravating things is to fast wind a X7R and have to wait the 2.5 to 3 minutes to have it finish a 1800 foot roll of tape.  Ha! Teac knew there was a problem and  released technical bulletins to make some corrections. Well I use a different approach in application of the 30Vdc supply to the motors only in fast wind mode. Does this work you might say? Well both fast winds with my modification finished the same roll of tape at 58 seconds. I have taken a signal out of the logic that signals the reel motor drive that it is doing fast wind mode. This then goes through some resistors and transistors to invert the signal to drive a TIP107 transistor that then sends the higher voltage to the motors. There is a diode that maintains the 14Vdc supply at play mode on those motors and that prevents the feed of the 30 Vdc supply back to the 14Vdc supply. I have tested this deck and it is going through more tests but if you want to get your deck corrected for this problem, contact me.

Well the first of my mods is out there and only time will tell if the client likes it. I have a feeling that anyone who has sat through the slow wind speeds will fine this less than a minute speed much better. I have obtained some further parts to build these kits. I just have to do the  schematic and instructions. I think the idea will be well received once people find out how well these decks can work.

Damping Silicone in 8ml bottles

This product is used to dampen the movement of left tension arms in Teac and other tape decks. Its Viscosity is 300,000 cSt.  The 8mL sized bottle should be enough to do 3-5 tension arms per bottle. As you probably already know this product is not easy to find. The product name is Dimethyl Polysiloxane. I offer this as a service to my fellow Service Technicians who can not afford to buy a Gallon of it for over $400.

I have used it successfully on a number of decks already. It does work.

Cost is $8.00 plus $7.00 shipping.

Contact me at skywavebe@sbcglobal.net to order one or a couple bottles.

They are in limited numbers.Silicone 8ml-2

They are clear after the bubbles rise. Probably can service 10-20 machines from one bottle.

What you need to know for Repairs

Over the last 45 years of service in the Electronics Industry, I have worked on anything from Coffee Pots, Rice cookers, VCR’s, Camcorders, Digital Betacam, and then Transmitters in the AM and FM Radio business.  There is a lot to see. But in working on consumer tape decks and amplifiers there are a few things that stick out for anyone wishing to repair electronics should watch out for.

They can be things like poor wave soldering of the boards. There is so little solder on these parts that the smallest bump or vibration will cause a failure of that circuit. Multiply this by 100- 200 joints in a machine and you have a real good chance that it will need repair sooner rather than later. Other things that can break weak joints are conditions of thermal cycling. Does the part have a heat sink on it or does it get hot? Well so does the joint. So many cycles will make the solder joint weak and it was develop a ring around the part lead and again an intermittent connection or break. Corrections done by a good Technician who knows how to solder using Kester 44 (Lead) solder will do wonders for the longevity of the unit.

That is not the only thing that causes failure. There is the infamous 10 V Electrolytic capacitor. These 10 V types have proven a very high failure part so that I often tell others that I am allergic to 10 V caps. Many a tape deck or other equipment that have this part are on borrowed time from when they are made. I just was working on a Teac Z6000 tape deck. Playback was lost on the left channel. Further examination indicated that the coupling cap was defective and must have had a bad connection inside. What value was it? 220uFd/ 10V. Not the type of part I would expect in a $1500 tape deck. Don’t feel bad Teac, Revox and Uher have their Frako caps too. They are notorious for shorting.

OK, Now for the X series tape decks from Teac. Some think that having dual capstan drive is a plus. Technicians can tell you what a headache they can be. There is sensitivity to belt length, belt position, how clean the pinch rollers are and dirt on the capstan shaft. However, what causes me to write this is that I have also found the the two conditions that are seen are either Skew or tape looping. Looping is when the tape comes away from the heads making a perfect loop down below them. This is most likely caused by a loose belt. Most all X series need a 16.8″ belt but some sell 17″ belts that are near the limit to not use them. They sometimes do not work and if they do only for 6 month. Marrs has the good belts at 16.8″ X .330″ wide.

Next there is Skew. This is when the tape travels off the straight path at the pinch roller. I have determined recently that some genius adjusted the head position on the head block so that they are tilted and THIS make the tape skew. Of course the machine never works like they adjust them. Just go turning all the head screw and you are sure to make the deck better- Yes after about $160 of Technicians work. Rule is don’t touch these screws you need a lot to put them back into position.. Please,I have more than enough work already.

Tascam 122 Mk III and Other models- 112 and so on: Gear

I am now at the point that I am taking orders for the gear that so many service shops and people need to fix their blinking transport lights problem. Teac does not have this part any more but I have had them made up. They are $30 plus the postage- I will not ship in a flat envelope like the $80 guy does on E bay. What does it look like-This is a Resin cast gear as were the original ones. Some call it gear B some Gear C. In the 122 Mk III parts diagram 4 the 4-34 part is what this is and was part number 5801474300 and sub’d to 9278377600.

122Gear wm

To obtain one or some, contact me at skywavebe@sbcglobal.netI take credit cards- MC, Visa and Discover and can take Paypal as well. The cost of obtaining the gears has gone up slightly so they are $30 each now. Also know that the mechanism must be cleaned and greased prior to use or the same problem can occur. I have never had a new one fail yet.

I can’t find anyone to make them for free!
