Not wanting to spend big money on old stuff... but wanting to stay "old-school" I first bought an A/C 30 with a pair of "green backs". It was the "last of" the British made amps, but it had problems so I returned it to the shop. I bought a Dr. Z Max 38 Senior, with tremolo and twin Alnico Blues... it was stolen. I replaced it with a slightly used 65 Amp SoDo... which was tasty, but I missed the reverb of the Dr. Z (and I missed the Tremelo of the Vox even more). My guy at the vintage shop had just brought in a 65 Amps London head w/ 2 x 12 cab. He basically swapped it out for the SoHo... I have never looked back. The 18 Watts is more than enough and the versatility (with that super sweet tremolo, and even sweeter "Marshall" side) was the perfect match for me.

Description:

Evolved from some of the Mid Sixties best low powered amplifiers. The 2xEL84, Cathode Biased, Class A sound is that of astonishing warmth, depth, harmonic richness all in a small package that allows big-amp sound on small stages, in the studio or at home.
Trem channel – 12AX7 based with a single tone knob and an organic Bias tremolo activated by a footswitch. This channel is the one for many of your classic British tones from your favorite Blues and Rock records.
Color Channel – EF86 (pentode) based with a tone knob and 6-way color switch that adjusts the mid focus. This channel is reminiscent of the British Invasion sound until you push it hard via the Booster Switch and then it flips into ultra-rich, harmonic saturation that defines modern day boutique amplifiers. Introduced in 2005.

Nice amp, good tones. Not class A, but most manufacturers lie about that also.
I don't really know much about circuitry, and it never crossed my mind that they would be less than truthful in their claims. I simply cut and pasted info from (the now defunct) manufacturer's specs. So, if it isn't a Class A amplifier, what is it?

Cathode biased, class AB. Cathode bias allows tubes to run at 100% MPD, so people think (or pretend to think) that the amp is running class A. Class A means each tube is conducting the full signal, no crossover. While it is possible to have tubes in parallel or push-pull, and still be running in class A, this is almost never the case. 2 EL84s in class A operation would make about 7 to 10 watts or so.

That’s really interesting. Thanks Paul

Ok, this thread pushed me into a rabbit hole yesterday. I was aware of 65 Amps but hadn't really looked closely. Lots of really interesting stuff. Most of them seem like variations of a Vox-meets-1974x Marshall. How accurate is that?

I have liked those sounds but haven't dug deep. One question I have based on some reading about the EF86 tube. One tube supplier wrote that they're very sensitive to amp vibrations and microphonics. How do you find the 65s to be in that arena? Is it an issue at gig volumes?

Very nice. I still have my SoHo but sadly don't use it as much as I would like at home or rehearsal or for gigs. Fantastic sound though.

I wanted - and still want - a London but at the time the SoHo's master voltage (not master volume, as 65 would point out) was a necessity.

Even at outdoor gigs I barely got the master past 9 o'clock. I did attend one rehearsal in a house with hardwood floors, high ceilings and a drummer intent on pounding as hard as he could. So I had the amp up to 11 or noon and thought the walls might crumble.
