OK I think for IC's and transistors I will stick to Mouse, SB or PPP been happy with those so far or maybe not as I have had trouble with transistors. Now I may have answered my own query as the builds that I socketed because the kits came with them work fine those I did not, not so well. So I plan to rectify that. Thanks again.

Thanks Brian for the Tayda lead. So these in lines will fit on the MBP boards it is hard to tell by the picture much cheaper than SB for sure.

Thanks I have sockets for 8 and 16 pin ICs now and triangle trans but not in lines which I think small bear has. You always need more parts eh?

Thx Brian I'll check it out. These boards are small...

Pictures of build

Reddesert There is continuity between the TP and the Drain, however does not appear to be between the tripot and TP. I will take a deeper look tomorrow. thx

Hi thanks for the feedback. I did replace the first J201 I had in and I am pretty sure it is in the right way. The switch is hooked up. I bought the J201 from skeyescraper on ebay I have one left what is the best way to test it? I have heard there are bad ones out there I have some on B/O from Mouser.

The curious thing is I get nothing at the TP which would be before the J201 and after the trim pot right? Still baffled.

Hi I am having a problem with the Fat Pants JR build. I get no sound past the J201 which I replaced to no avail. The voltages are:

I 9.7
G 0

IC1 (LT1054)
1 1.40
2 5.24
3 0
4 .9mv
5 0
6 2.543
7 1.405
8 9.42

J201
D 3.3mv
S 10mv
G 0

As I noted the J201 is not receiving the correct voltages. The Trim Pot does in fact have 27.5 v at its 3 pins but the TP has a minimal 3mv.

I used a sound probe from the input thru the circuit. There is sound up to the J201 G pin but nothing after.

Is the C12 cap the problem or is it something else?

Thanks

Mike
