Re: LF: Racal 5501

Hi Laurie.

 

I recall that when I first powered up my Decca, it had low output on one module. That turned out to be a blown diode in the power recovery unit.  - It's been so long I've forgotten the full detail.

Hi Laurie, 
I have a spare Power Amp Module 5501 but it is also faulty. However, the fault is clear - it just has blown power FETs. 
You can have it for free - you should be able to make a good one from the two faulty ones 
I thought I had some spare power FETs but I can't find them at the moment
