Friedman Vintage Plexi

[LP Freak]

I thought Dave had been saying "sonic clone" since obviously there are some circuit changes with the variac switch and master volume. Either way it sounds amazing in the clips so far. I use a FX loop live so my only interest in an amp like this live would be for recording and can't justify the price but I sure would love to spend some time with one someday. Can't wait for the comparisons with the SL67s.

Yes, I heard the same…a sonic recreation

Probably "sonic recreation" because there's actual improvements you could make to the original PCBs to improve noise/etc without affecting the tone.

To me it is between this, the SUHR Mark II and the Tone King Royalist Mark III. The Royalist has the best price point from what I can tell. They are all doing the same thing, variac I'd just buy for 80$. Dave has mentioned you don't even need to bias the output tubes hotter, it just sounds a bit better.

Is the Friedman automatically biased hotter when it's on the Variac setting?

Yes

 

[valve]

Yes

And this automatically happens with every (marshall) tube amp circuit if you drop the Voltage or some engineering went into the friedmann specifically on this behaviour?

It designed into the variac. I’m sure it’s similar to what George uses on the Metro amps

You have to modify the bias circuit, the bias doesn't magically go up if you lower the input voltage to the amp. There are two ways to do it, at the primary or at the secondary. I suspect this is at the primary since Dave has mentioned the lowering of the heater voltage is part of the sound when using the variac.

I checked the prices on George's amps.... yikes.

$2799 per Dave. I gotta have a loop, so my interest went out the window.

The new Morris UK'68 has a loop because the Master Volume is pre-phase invertor. The amp is designed to sound like a cranked up browned out Plexi if that's what you're looking for.

It looks more similar to the Metroplex MKII in its design, whereas the Friedman and the Suhr are more direct Plexi clones.

Yeah. He has a Plexi clone running at lower voltage called the '68 Brownout.... but it has no loop! ;-) (nor a MV)

Interesting, you don't hear much about his amps... good prices on them though. Sounds good here but maybe a little shy on the gain that I hear in the Friedman

Try this one... (highly attenuated -32dB!)

I assumed he said it that way intentionally so he wouldn’t get sued.

Sued for what?

 

[RedB4Black]

Sued for what?

Saying it’s an exact copy of the amp. Regardless of whether a suit has merit, he could still get sued….incurring legal expense

No sense inviting it

Why would he say it’s an exact copy when it’s not?

He said in the screen shot above it’s the exact circuit. Looking at it, it’s not an exact copy obviously.

Well, it seems we have an answer about the new PPIMV (from the SLOClone forum) :

Here is the interestng part of the video of the message :



It seems based on a Trainwreck Type-3 Master Volume, except this latter uses a 1Meg dual single pot :

https://robrobinette.com/Generic_Tube_Amp_Mods.htm#Lar-Mar_MV

So two questions now :
- Why a 250K dual pot instead of a 1Meg ?
- If it is an inprovment, why did we need to wait for 2024 for it ?

Dave's been using this MV in mods for a while. I had him do it a few years ago to a Plexi I used to have.

I'd think of it more as "why did it take him so long to put out a production Plexi".
