Re: Shin-ei/Univox Uni-Vibe [Replica Files]
hFe really doesn't make a difference in this circuit. But you can put a transistor with the highest hFe as Q1.

Re: Marshall JCM1H or JTM1H schematics
Ok, so C15 should be in the signal path...where? Also, I don't see any 4M7 resistor... Are you talking about in this schematic? Thats just it there is no 4M7 in connection with the 100n being in the correct location. Im talking about the pcb in the thread not this schematic that someone posted. Sig...

Re: Marshall SL5
Looking at the EL34 datasheet:
With class A operation with Va= 250V, Vg2=250 and Rk=107R (very close parametrs to those in SL5)
primary impedance should be 2000 Ohms, minimum DC bias current 100mA.

Re: Vintage Distortion Plus using U741cp?
Use of the diodes make different opamps sound more similar, but it doesn't mean they sound the same.

Re: Vintage Distortion Plus using U741cp?
Not exactly. In Distortion+ diodes are hardclipping, so they clip signal boosted by opamp. And if they clip earlier than opamp (I presume they are) then difference between opamps minimized.

Re: Death By Audio - Supersonic Fuzz Gun [traced]
I've encountered this problem: in gate mode with Fuzz and Density maxed out (sometimes with Bias maxed) couple of seconds (4s?) after muting strings appears background noise (depending on Bias setting it's shorter or longer). I've read in PGS demo comments that one person had similar issue in factor...

Marshall SL5
Hello, have you heard about new mini Marshall 5W combo based on Slash' Super Lead? Sounds pretty nice: https://www.youtube.com/watch?v=d2WYDRLsJRo I'm enclosing schematic. Wondering about OT impedance and pretty hot biased EL34 (only 120ohm cathode resistor) however maybe it's because low anode volt...
