Was really liking the amp, I had added some capacitance to the power caps and paralleled a film cap with the last stage power cap. Tube rolled with a ton of different 6080 types (my favorite was the graphite plate tungsol/red bank types), also added parallel resistors to the volume control to...

Ok, somewhat on topic....so I got the Abbey Road super deluxe set that has the blewray with the highres versions as well as Atmos. I can burn the 96/24 stereo, but I have no idea on how to access or playback the Atmos version. Yes, I don’t have a multi speaker system, I just wanted to hear the...

Makes me wonder if there is a “tube head” in customs...and the tubes that come across his desk are the ones that get confiscated and “destroyed”. The nanny state has to protect its citizens.

I’m a tube roller from my guitar amp days, just getting into headphones and HP amps. I have a modified little bear p7, and am building my own amp based on that. I have just about everything 6AS7/6080 now, but still on the lookout for a Bendix graphite plate 6080 and a domino plate Tung-Sol 6AS7.

Heh, heh, heh..... $157.50+$14 shipping.

Since a lot of film/oil caps for OTL outputs are huge to get high capacitence at the needed voltage ratings, is there any reason you would not want to mount them outside of the amp chassis (like power supply caps often are mounted) if you have limited interior space? Especially motor run caps...

They look like RCA’s.

I have a question about 6336/6528 tubes. I know they need about twice the heater current as 6080/6as7 etc., but they also have about 2x the plate dissipation. If you wanted to get the most out of these tubes (in an OTL amp) should you adjust the cathode resistors to get 2x the current of a 6080?

There’s a bunch of 7236’s on ebag now for ~$30-40 US. Not counting shipping.

Thanks for the suggestions. You wouldn’t happen to know the interior space dimensions, like from the board to both sides of the case? My P7 is at work, so I won’t be able to measure it until tomorrow. I’m curious how much space here is to add larger caps.

I just got a LB P7. I like what I hear from it so far, but I’m interested in seeing what can be done with it. I’m going to tube roll with it in stock form, then I might fiddle around with bypassing the output electrolytic capacitors with different film caps, and possibly the changing the...

It was $350 on the latest massdump. It ships the end of this month, so I’ll soon find out.
