Sounding good. Is this with the Mesas speaker ? I think I can hear the speaker or the power section adding a bit too much lower mid section frequencies to my taste to not make the sound clear or balanced. What is Your settings of the potentiometers on the amp/guitar?
it is celest g12-100..yes you are right about low notes, (bass knob at 4/10, treble and mids are on 2/10) i had it too much besides this setting (i'm searching best ways to tame it) .. in power supply i have 47 uF to anodes so i think that this will do and clean works well.. 0.1 uF couplers to output PCL tubes are next suspicious
I had a few minutes to record another clip of the amp. I tried the Kleinulator (the early fet version) on the loop but it thinned the sound on both serial and parallel mode. Oddly enough the Boss delay sounded best without the Kleinulator.
That's waaayy over the top incredible guitar playing to my ears! Just amazing technique.
IF I heard a guitarist having that MP3 on a CD, I'd be looking to collect everything they've recorded. Sort of like I've done with Carlton and Fourplay's stuff.
It sounded like the amp was starting to either oscillate or feedback in places? Do you know which it was doing? Oscillation is somewhat problematic, but feedback can be musical and somewhat useful, IMO.
And I am wondering if you had held a note (for some length like 5 seconds or more) if would've made either that oscillation or feedback?
Does your band typically play that type of great grooves which sounds kind of like a blend of rock, funk and jazz to my ears. Whatever it is, I love it!
Jeff thanks for the very nice comments. I had the drive almost full and was sitting too close on the amp. On the oscillation point on the recording I turned the guitar volume at full. The layout is also not ready and that is propably one reason for it.
Our band plays more country and southern rock style. These soundclips of the amps I've built are just quick ideas from my head. And they sound like that also... ;O)
Mat have you given thought to modding the tonestack further given you are running controls down on the treble, and not using the bright switch?
Then the guy thats tried the circuit using different tubes appears to be having the same result.
Maybe lowering the slope resistor, perhaps increasing the first cathode byoass from 5uf to 25uf and dropping the second stage bypass altogether?
Just a thought, will find out for myself soon enough as my trannies have arrived

I'm afraid loosing the definition of the OD with 25uF on the V1. Haven't tried it so far. All my energy is on the new build. Definitely will get back to the original build with new layout/turret board.
heya Jeff, on the layout, you have the 250K OD drive pot feeding the EF86 from the wiper. On the schematic you have the EF86 grid connected to the right side lug. Cheers buddy, Don

I'm just wiring that section up at the moment, I can't see what you mean, but I am not using the OD tone pot as I have an HRM board in this.
I would be grateful if you could post a layout/ schemo showing this, if only to save my butt here
EDIT: ah, I think I see what you mean - OD1 and OD2 on the layout.
Well I think for now I will go for the layout, as it seems the same as the original mini HRM with the 5879
