Tube Amp Archive

curious, has anyone here modded one of the AC4TV's to sound better?

mine is great clean, but cranked up it doesn't give up the goods like a good vox....have been considering a HW but it can't be that difficult of a circuit to mod a bit?

interesting, will try, thanks!!

I want to try removing the NFB from my '78 ultralinear super reverb is it as simple as disconecting the wire that I've marked in RED, from the speaker jack? big pics, might take a bit to load [img:2560:1920]http://kt66.netii.net/images/superr/red.jpg[/img] clean pic: [img:2560:1920]http://kt66.netii...

I loved reading Chuck Yeager's autobiography, couldn't put it down. highly recommended

back on topic...man that sucks I really liked those winged C tubes!!


RIP =C=

ah, good idea!!

is there a schematic repository we can dump this stuff in?

is schem heaven still online?

ah, interesting, I saw the thread on the R600 lectralab but didn't realize they did the H305 as well although that is the H305A...will have to check out the diffs here is the H305 schem on the amp [img:1024:768]http://bolero.comyr.com/images/harmonyH305schem/H305%20schematic%20%28Large%29.jpg[/img] ...

hey I have one of these, bought it for guitar after trying another one out that sounded fantastic this doesn't quite sound as good, I'm wondering if anyone knows about the changes they made to the H-305 circuit over the years? or any adjustments ppl have done it is a cool little amp: 1x12 combo, 2x6...
