SINGLE 6AQ5 TUBE AMP UPDATE

it also has a couple of toggle switches, i think one of them jumpers pins on the power tube sockets for trying out different tube types, the other one i don't know. it has a volume, super high treble(or presence?), a mid, and a low control. it employs two 12ax7s and a 5ењ“ rectifier. just less of it.Hmm whats up with the new 'emoticons'.i think i prefer the 'lo fi' ones.ДЄnywho, i picked up a homebuilt PP 6aq5 guitar amp from some tinkerer. The one thing that I did think was significant was that the sound of the EL95 was so similar to the EL84. I'm lazy enough that once it started sounding cool, I started using it and never made it back to really study it. Better technique would really be in order to make the most out this design. In all honesty, I did not invest enough in tweaking this to any specific tube, but rather swapped tubes around I got a good sound. In the photo I attached it has the EL84 in it. I had originally designed it around the 6G6 octal, but that didn't sound too good. In the end I got the very best sounds out of this amp using either a el84 or an EL95. As you can see, I could exchange 8 pin, 9 pin, and 7 pin tubes. Don't hold up your project waiting though cuz I'm slower than molasses on these kinda things.ДЄnyway, my amp was a single ended amp that I was using to compare various output tubes.

SINGLE 6AQ5 TUBE AMP UPDATE

I'll see if I can bring myself to open that amp up and take some honest measurements and then update the drawing. If I recall correctly, my power transformer was 250-0-250. the voltages listed I think I put down as place holders and they are not real.

It has been awhile since I did this, but I found the drawing that I started with. I am glad to hear that those bottles are nice ones because I happen to have a pair of them in my stash and would like to use them to some project. Harryk wrote: RJ! When you made an amp with EL95 tubes, was it a single ended or push pull configuration? How much voltage you had in power tube plates and what was dissipation? What kind of PI did you have in it? My aim is to make an amp with Express preamp with 2ењЋL95 tubes. Please post back with us when you get something going, I'd be quite curious what you come up with.

but didn't sound as good as the others I mentioned. The 6AK5, 6AN5, and the 9001 are really short stubby rascals and if you want to make something really small, these are kinda interesting. My all time favorite small venue gig amp is an ecc99 PP triode. I've also tried several triode outputs in push pull and had reasonable success. A 6AK6 is my next favorite with more of a 6V6 sound to me. Very EL84ish in sound, but only 3 or 4 watts. but I think the best sound I ever got was from an EL95. I've used a bunch of different 7 pin tubes icluding: 6AK6, 9001, 6AK5, 6AQ5, 6AN5, 6AG6, 6AU6. I'm inclined to believe that the human ear really hears things better when it's louder and thus leads us to believe amps sound better when they get louder. S2 - I've been chasin' big tone in small tubes for a long time and I've found several answers.
