I've often wished my amp had less power, I've never wished it had more. So I'd rather just not build an amp that requires a half-power switch.
Why...

Essentially, this is the TMB version of the Marshall 18-watt, as seen elsewhere on the internet.
I'm not sure your tone control on the normal...

Soldano SLO is a classic example, but most brand new amp (including Marshalls) are this way. Of course, when it's PCB you can do a lot of things with whatever...

I always find it funny when those debate of modding vs building vs buying erupt on a forum like this... I think it's safe to assume we're all here cause we...

Not to mention it's already pretty far from an actual Marshall 1987 circuit
(What's the point of building if you're not going to experiment with it...

Hahaha, what I mean is that I like the sound of a tube amp that is struggling to keep up, like old tweed Fenders. If I swap 6V6s in there, the massive power...

I have the classic 1K right now, would 2K be enough to make an audible difference?
Maybe I'm not helping myself with the big fat choke though...

I don't really like PI drive... had a PPIMV and removed it. Went with a regular MV in the end.
I'm not looking for more gain, just want the...

Part of that is because most guitar players are not technicians and play series-produced amps with PCB design. It's much easier to swap tubes in those than...

Lowering my 50W Plexi clone efficiency
2 years after building this amp (think Marshall 1987 with 2 EL34, cascaded preamp and no NFB), it is clear to me: I will never need that much headroom....

Currently play through a 2X KT77 (around 60-70W, haven't scoped it) with an oversized 2X12 (G12T-75 and WGS Reaper HP 50W G12H clone). I can play Metallica...

Yeah, I mostly mean examples of tube preamps circuits that are known to work well with an SS power stage.
I'm much more into the Marshall type...

Well, the SS part I'll probably just bridge a pair of LM3886 (or two pairs and make it a stereo affair) or use an off-the-shelf unit.
It's...

Hybrid designs with all-tube preamp?
Anyone has some cool hybrid designs they could refer me to?
I'm interested in trying to build one, where all the juicy tone would be created...

Thanks!
Remember that your power output is limited by the power supply. The 6K6GTs can push close to 10W per pair, but you'd need more voltage...

Hi NKM795,
Your schematic for 2X 6V6 probably works, the trick is simply to change the OT primary impedance and cathode resistor accordingly....

I love mine, it's clear yet not shrill.
But granted, I haven't built a similar amp with another transformer so I've got no comparison basis...

His thinking might be based on the fact that true Class A amplifiers dissipate a lot of power at idle. However, what he fails to understand is that this idle...

Yep, Vox has been getting by with calling their AC15/AC30 "Class A" for so long that nobody questions it anymore.
The common marketing approach...
