I had same prob w/my unit. It's a simple fix. Use denatured alcohol to clean the metal surfaces, and then oil all sparingly I will send .pdf manual copies tomorrow (Friday) to all who asked. Just got back from a long trip to SoCal.

The way to get rid of low frequency multiple harmonics is to design the room from the beginning. Afterwards it is tough but doable. 90 degree cormners cause all the probs. Bass traps were designed to rid the room of the additional harmonics crreated from a fundamental harmonic.

For oil go to an ACE hardware store and get the Zoom Spout oiler. Remove, clean, and oil the two tensioner pulleys as well as the capstan roller. I need your e-mail to send a .pdf.

remove all the rollers and tape guides and clean thoroughly and then lubricate with very fine oil. Same thing happened to mine. Your brakes also need adjustment. Let me know if you need a .pdf copy of the service manual.

Some time ago in Brooklyn if you asked that you would have gotten a response of: "what way did you come in!!!"

Let's hope the student loan will give you good future returns.

I have the manuals. Speak up who wants one.

Did you mean hair dockta?

You do mean 6 screw precision reels right? Can you wait about 90 days? What have you been soldering- 48 sound cards?

I supplied many components to Carver, and it would not surprise me to learn that some equipment you mentioned has components we supplied. Bob Carver was (is) a very clever engineer/designer, and he did present many unique offerings to the industry. I think he's skiing in Vail now. He might...

Good advice, technoplayer. Maybe time to replace belts as well while in there lubricating. A good source for SONY info, belts, etc is Vintage Electronics Sales, Repair, Parts for Marantz, Pioneer, Teac, Etc.

Well if the speed starts to warble it may be the motor run capacitors faling!

I was unaware of the capstan adjustments until I was recently working on my 122 cassette player.

Could be bad motor run capacitors for which Sony is notorious. Each motor has one and they are either 1.5 or 2.0 mfd. They run about $14.00 each which is absurd.

Here's a S/M for that animal at a decent price as well: TASCAM 388 STUDIO 8 * REPAIR / SERVICE MANUAL - eBay (item 180593605462 end time Feb-26-11 08:22:14 PST)

There is frequently capstan bottom bearing adjustment specified in the Service Manuals. Get a copy of the S/M and check that out. If the pitch changed as you said then maybe it's not the bearing but the adjustment point that rests on the bottom of capstan shaft.

Use lube sparingly but get Zoom Spout oil at ACE Hardware. Might want to check the capstan cover as well. Might be dirty and spinning oddly.

Think of it as a free heat sink!

You are maiking me weak in the knees! I hate when I get encouraged to follow suit!

read an article to extend the leads to mount heavy duty rectifier diodes about 1/4" above the board for better cooling and less possible board damage. This is a good case in point.
