OEM genuine TCA561 controller IC for Revox A700 and Studer A67 and early B67
Part No.  TCA561
Fits ALL models that use the  TCA 561 controller IC.  (not for later versions).
The part is sourced as a OEM component and not a generic replacement - ie exact part no. and specs. We only source from reliable manufacturers whom we have been dealing with for many years. No NOS (new old stock) or 2nd hand items!!  
They are an ouch price but sorry, I cant source any cheaper! At least we have them and they can be replaced. 
WARNING. PLEASE NOTE - semiconductors sold are non returnable for obvious reasons. If you DO NOT recap - ie replace the tape transport board electrolytics / tantalums AND PSU, motor and suppression capacitors before you replace any TCA561 - then you are being foolish and may blow the new IC's. CONSIDER our full electronic recap and update kit. IC's go faulty in the 1st place because many capacitors are old and faulty.  
SPECIAL OFFER.  If you only want to purchase these rare IC's on their without fully recapping your machine with our kit and detailed instructions - you are foolish.   To encourage you to do the right thing here is what we can offer. IF you purchase in addition to these IC's our A700 electronic kit or full monty kit (NOT basic) then we will give you a $85 discount per IC.  This will be passed as a credit on ebay once you have purchased.  

PLEASE NOTE VERY IMPORTANT. I REPEAT.  IC's, semiconductors and optics once purchased and delivered are non returnable. Replacing an IC or semiconductor into a dubious or possibly faulty machine can blow it as other problems may be present. All semiconductors are new and tested before they leave our facility. You are urged to do a full recap of your machine and then test all PSU voltages before troubleshooting and replacing any IC. I repeat - no returns on semiconductors or complaints / cases opened 'it doesnt work', 'not as described' etc. Apologies if this seems harsh but all items in good faith leave our workshop in good working order and simply replacing semiconductors may just not be the solution your own subjective fault funding has concluded.  I am happy to discuss your symptoms and try to help you diagnose problems before you purchase. Please avail yourself of this offer.

 NAGRAVOX PARTS – Important Information. 

In respect of this listing only. We don’t really want to sell parts only on ebay! Our parts are listed on ebay for the benefit of customers who, at the same time purchase a kit from us.  We don’t really wish to cater for occasional spare part sales which, to be blunt is a hassle and time consuming and which, in most cases, is unlikely to solve likely hidden or soon to surface problems on your Revox, Studer or Nagra equipment. Please give consideration and look at our kits in other listings in our store.  Thanks for your consideration and hopefully understanding and I hope we can help in restoring your machine.
