Hi hypnos1, glad you are enjoying that great Amp, have read a lot about it! Unfortunately I havent been able to run the C3Gs with a decent pair of powertubes, the adapters I ordered didnt work, my big shame, well, as I am expecting a shipment from china that carries the adapters Mike sugested, along with some 9 pin socket savers. I have been reading this thread a lot and now I wonder if you could assist me in running some Tung-Sol 6080 (already got them), As I could see you ran this project before! Well the thing is that I made a diagram and just want to make sure everything is in order, will be a very fun weekend project anytime soon. Please check the image and tell me what would you suggest in case something is missing, Help will be very much appreciated cheers!
Hi WeirdChild...very impressive! And glad you already know about gibosi's mention re disconnecting from the LD's heater supply.
I hope you have no problems with hum from the external PS - if you do get any at all, try connecting the DC neg. out to a mains Earth point.
And I wish you all the best with your project - you will be amazed at the difference! But I'm so sorry about your C3gs....I do hope the new adapters work OK - these tubes will also take your amp to whole new levels...CHEERS!
