I love this thing but it stopped working after about a week, I kind of a newb and Scott doesn't seem eager to help me troubleshoot so here I am.
Neither audio channel is working, the pilot light does not come on, but the 48v phantom power lights light-up when pressed. I tested the psu according to the schematic and it seems that I'm reading really low on everything compared to Scott's reference points starting with around 34vdc at V1, (R34), and ending with the meter reading -.5 at V9, (R52), would that be the power transformer you think?
Bad Power Transformer On Hamptone JFET?

3 quick things:
1> is there any chance that it was wired for 220V input?
2> Please post a clearer schematic, so I can make out the node names.
3> Make your own version of the VDC/VAC table and post it.
If you've got any voltage anywhere at all, it's unlikely that the transformer is blown.

Hamptone schematic
Hello:
I added onto this older thread because it contained a partial answer...
I found the 2002-ish Scott Hampton Tape Op articles but they seem to lack schematics, referred to as 'Figure 3' etc.
Scott seems to be a full-bore manufacturer now, vs. 2002, so perhaps that's why the manuals on his site done't seem to have schematics.
Are they not visible here because an archive subscription is necessary?
Or maybe I didn't look hard enough. I got the out-dated Internet Explorer warning and tried a different PC with Chrome but don't see "Figure X' illustrations.
Thank you
