Tube Amp Archive

So Im sure everyone is familiar with Morgan, Matchless, Badcat etc that have the light up logo plates. Anybody know how they are doing that? I have one of the amps mentioned above and it has vellum paper on the back of the badge part to diffuse the light. I'm assuming its a laser cut/engraved piece ...

Fantastic! this is what I was hoping to hear!

Hey everybody, So I have an AO35 that I did the standard old Carmen Ghia thing to and it was just a 'meh' project that kinda fizzled out. So I've been wanting to do an 18watt Lite IIb for awhile now and thought :idea: I'll use the AO35 transformers for that vintage Mojo! Fast forward to me wiring up...

Hey everybody, working on a lite IIB build. I'm going to try a few volume options including VVR, PPIMV, both, etc... Can someone point me in the direction of a PPIMV wiring for an 18watt? I can only find a few variations on different types of 18watts. Also, curious if a Spitfire MV would work, becau...

Thanks guys!

You've given me ideas for the next few amps!

hey everyone, I'm mostly a lurker around here, but I love this forum and its wealth of knowledge. I just finished up a Rocket for a buddy and I've got the itch to do another build for myself, but I can't nail down what to build. My main amp is an AC15 normal channel style amp (Morgan AC20), so I wou...

The input with a shielded cable is never a bad idea. And I'd have lifted it farther away from the heater wire to pin 9, and then cross the heater at more of a 90 degree angle. The cathode bias ground wire on my builds goes to the screw on the socket of the closest EL84. I too now wrap components ar...

Tone wise, one of the best amps, if not the best, I've ever played through.

Noise wise, pretty darn quiet. Has a really subtle hum but the owner never even noticed it.

I know you weren't looking for solder critique, but I just wanted to mention, some of the turrets look barely soldered. Not trying to be nitpicky; just want to let you know. Personally, if I find that all my solder is running down inside the turret, I back off the heat on my iron a touch. Others ma...

Hey everyone, I just finished this RJ Rocket and thought I would post it and ask for some thoughts on things I could improve upon for next time, which will be pretty soon. It is my first TW style build. I realize some of my joints are not the prettiest so I don't really need that pointed out. But I ...

Hey everyone, Im new around here. I'm still a noob at amp building so forgive me for sounding as such... Thanks to this greart forum I just finished up an RJ rocket and am really please with it, as is the friend I built it for. I would like to build another for myself now. The Zwreck has been at the...

So right now I have an amp, from what I can see is an exact AC15 (ef86) normal channel only, clone. There is just something about it I don't like. I don't want to post the builders name, because he is small shop guy... Last year I had a Morgan AC20Deluxe head, which is also a Normal channel (ac30?) ...

Hey everyone, long time lurker, first time poster. I have an AO35 on the way. I originally wanted to do a project Carmen Ghia conversion, but now I'm kinda leaning towards doing a super 17. So does anybody have any info on the super17? Layout or schem? I've found a lot of info on the ao35 conversion...
