My amplifier went out in this sub, so I am selling it for repair
$400 or OBOBI had the MOSFETS replaced for $225.
Output capacitors are good
Power transformer is good Not sure why it is not functioning Includes entire amplifier back plate and all electronics you see in picture and all buttons and knobs
REL BRTITANIA B1 Cosmetic Condition = 8 of 10 I don’t know exactly what needs to be repaired. There were NO symptoms so to speak, it just went quiet. The amp plate still powers on, just no audio output.
A few things: 1.) I had it looked at here at Vintage Voltage Repair, and they weren’t familiar with REL stuff so it was not repaired.
2.) HOWEVER, I went ahead and had the 4 MOSFETs replaced anyway because I figured that would be a good idea no matter what. So you are getting an amp with 4 brand new MOSFETs about one month ago. $225 worth (still have the old ones too)
3.) The toroid is still good, the large output capacitors are still good, and like I mentioned brand new MOSFETs. So the positive is that all the big expensive parts are still good.
4.) A visual inspection shows no damage of any kind that we can tell. No bursting capacitors, no bad circuit traces, and no burnt out resistors. So overall, visually can’t see what is not working.
