According to the PRB database, the belts you need are like this-
FRX11.3, SCX5.6, SCQ6.0, SCY6.0 the last numbers are the IC or inner circumference and the belts can be sourced at Kens Electronics in Michigan under the belts section. Of course if you have the time and want to save money you could do the research to find out the thickness of these belts- we know the size already and order from Consolidated Electronics where they should have all of these cheaper. If you want the least amount of trouble just order from Marrs Communications as he has the right kit made for you without your research. I have ordered belts from all these places over the years.

Could be just a failed fuse inside. It's replacement might restore power, but if it fails again, then there's an overload caused by a short-circuited part probably in the power supply section, where you will find that fuse.

On Kenwood CT 2050, tape speed varies near end of reel and stops prior to end of reel

Many cassette units have trouble handling 120 min tapes. You seem to have taken care of some of the problem areas but in my experience I would suspect the belts have stretched or aged. If this an older deck, the motor may be weakening. It can be the source of the problems you describe

Technics Tape Deck RS-M227X. VU needles jump to the maximum right

More than likely the pre-amp IC has failed! Trace the wires from the VU meters back they should locate the source of the problem. Remember it will be something common to both channels!

Tacsam DA 30 has no playback

Chances are that pre-amp IC that controls both channels has failed. Follow the wires from the tape head and trace the signal. Better still start with the output of the deck and trace backwards. If you touch the audio circuit with an insulated screwdriver (don't short anything) it should buzz. when you find something that buzzes on one side (coming out) but doesn't buzz on the otherside (signal going in) then you have found what needs to be replaced.
PS don't touch the power section.

Exact same unit -- will not play tapes, does FFWD/ RWD

next time please specify your problem rather than just sayng same problem it might help get you more advice

as for the belt use a small elastic same as belt or get a plyable ruber o ring from auto parts store
ruber band is best as it wil slip less and they are cheeper than origal\nal belt and easier to find

Records on right channel only so only get music from right speake

If you are recording from an outside source check the connections are good. If it does it from both IE dubbing and external it is possibly that a wire has detached from the head of the record head. The other likely source is the record amp inside the deck. Trace the leads from the Tape head (recording one) and see if you can locate a switch, these can get dirt on the contacts and cut out channels (clean with Servisol video 40). It could also be the electronics especially the amp chip!
If not then the head itself may have gone.

Reel to reel belt replacement

ITS been a long time since I replace BELTS for VCRs and REEL to REEL , what I suggest is , if youre very handy with tools and know your way around electronics, you can perform the replacement of the belt, open REEL TO REEL to access where BELT is located , study how is install , and remove ONLY the parts thats blocking you to remove OLD belt,memorize the order which you remove the neccesary parts
then install new belt , and install back parts in the order that was remove , hope this helps , good luck , AJ

Rca rs 2620 power but no audio

I had the sane problem: No audio out from any source. Although I was unable to find a schematic or service manual, I did find the defective part was labeled on the circuit board as Q401 and replaced it with RadioShack part number 276-2009 (MPS2222A NPN Transistor TO-92 case NPN silicon). This is not an exact match, but is available at most RadioShack locations for under $1 and has fixed the problem.
