As pictured.
Set for 70V rails.
1st GB boards with NFB trace mod.
10k input impedance.
Outputs NJW1302/3281 Hfe matched within 0.5% and 5% between NPN/PNP.
Drivers Sanken 4883A/1859A HFE matched.
Predrivers KSC3503E/KSA1381E HFE matched.
Q1/Q2 Q3/Q4 Q5/Q6 LTP transistors HFE and Vbe matched, 0.1% H8 resistors in the LTP.
VAS KSC3503E. All other toshibas.
Surplus to requirements - I have 6 wolverine channels at the moment so these to a good home!
------------SOLD --------
and I'll cover 50USD of shipping worldwide (buyer pay extra over) from NZ (would likely make it free for NZ/AUS).

Also have a Cobra S2 70V power supply spare if anyone is interested (outputs would need upgrading if used with the above board)
Hi Mainframe, do you still have the Cobra S2 SMPS available and if so, how much do you want for it?
I need it for a Wolverine EF3-4 V4.2 / IPS V4.9 with +/- 71V Rail Voltage. Is the SMPS suitable for that?
And what do you mean with outputs needing upgrading?
Cheers,
Walter
