Newer more efficient speakers and a smaller room mean that I won't be building these
after all, so up for grabs are the PC boards and critical parts for building a dual
mono single-ended F4. That translates into 12 Peter Daniel F4 amp boards, 2 cviller's
PSU boards, and 4 of his TO-247 diode boards, and two sets of critical parts and
matched FETs from TechDIY, which includes:
2
Q3..Q8
IRFP240 and IRFP9240 Matched Triplet
1
Q1
2SK170BL "N" JFET
1
Q2
2SJ74BL "P" JFET
1
Q11
TL431 or PM431 Shunt Reg
2
D1,D2
1N4736 Zener Diode
6
R16..R21
0.47Ω 5W source resistors
4
C1..C4
220μF 35VDC Elna Silk Electrolytic Cap
-------
Altogether this represents $145 worth of goodies. Will sell the lot for $120 as
everything is new and untouched -- tech diy package is sealed as are cviller's pcboards. Shipping in conus is on me, and no fees for Paypal.
Thanks,
Jimm
