The compensation remains unchanged. Sensitivity is set in the resistor divider before the input of Alps potentiometer - see the PCB photo, though the older version (R1,R2,R101,R102 here), though keeping the input impedance of 10kohm per channel. BTW, phase margin is about 63 degrees and the loop-gain curve crosses 0dB at almost 6MHz.

Thanks everyone who has been interested in the boards. They are already on the FedEx plane and should be delivered to Prague on Monday, May 19. At the moment, all the boards are reserved. I need two of them for testing with Linear Systems LSK parts and the remaining 13 pcs are reserved to:
Please (those who are listed above), send me your PayPal addresses to the PM, or you may contact me through email in my web page. Even overseas postage seems to be quite reasonable, less than a PCB price.

I have decided to add two pairs of the wonderful Hitachi MOSFET 2SJ77 / 2SK214 as an extra bonus to the ten first customers.

This will of course work, just by increasing resistor R8 value - the one between the Sources of the JFETs.
I suppose the package should be lost. did you write my phone number.or can you change it.

You should not post all your address etc. in the thread (and you should ask mods to remove, if you cannot do yourself anymore).
