Hello I recently Sent my Blue Sierra Amp to Factory in Maryland to have it repaired ,A previous owner attempted a repair on rectifier diodes and did a bad job so the factory repaired them and replaced 1ea 100uf Electrolytic mains cap that was worn .they did a fast great turnaround on amp after testing my amp the filiment fuse blew more than once and finally got that stable it sounds terrible very thin and fizzy low power. Tested speaker and all good. I really don't know what to do at this point it cost me alot for shipping and repairs and can't afford to send it back. This amp used to sound incredible when new.

Yes Thank you I have sent an Email to PRS customer service about the amps issues,It's just Surprising there techs would let this get by them.I have built a number of amps and have done hundreds of repair and service work but wanted this done by the factory and still do.

They’ve been very equitable on shipping for me when the problem is theirs. I hope they’ll do the same for you. As the owner of two CAD amps, I can say that I know what you mean when you say PRS CAD amps sound incredible.

That's great to hear.
I'm not surprised! They're great to work with.
Hi Greywolf ,Wanted to ask about your Blue Sierra amp, Does break pretty easy when driving it with a single coil guitar? In other words when master vol cranked up is it fairly clean until Guitar volume maxes out .trying to get a feel with my amp. Its My First PRS amp. Been playing 5E3 Deluxe build .
Well Bummed out that my Blue Sierra amp goes back to factory again for repairs but want it sounding right and not blowing fuses , It's obviously drawing too much current in power stage, It seems not to have enough clean headroom before breaking up. Just doesn't sound right. PRS Service has been great Sent me shipping tag all paid .Great Folks
With the KT77's you can bring the Master up way up and it is SRV clean, If you want dirt as soon as the Volume ( pre amp) goes above 3 your in crunch territory. With the EL34's it broke up early period . If I'm after a Derek Trucks/ Carlos vibe the Volume gain comes more into play .
The guy who sold it to me didn't like the always on crunch of the stock power tubes. It's a shame he didn't explore other options .
The Gold Lion Cryo KT77's aren't cheap $92.95 each .. but they are a fave of audiophiles and they get better with age .

That's good Info,Thank you . I did notice with 6L6 tubes The amp breaks up pretty quick when you bump up the vol, gain. Was not sure this was right due to the trouble this amp has given me. I have a good collection of vintage tubes some sets of Old Tungsol 5881,Mullard fx2 EL34 but no KT77 Many good preamp tubes so when I am sure this amp is right I will experiment with tubes. I play RnB Rock,Blues.
