First I want to apologise to the inmates who replied
to my queries about my H3 with no replies from me-
I will try to get back into that when I have a little time-
please be assured I appreciate your input.

Second, my H3 uses 6HB5 outputs, but is labeled on the chassis
for 6HJ5 tubes. The above pic is my set of biasing instructions
with changes for my amp. I can strongly assume that the crossed out
numbers apply to your amp with 6HJ5 tubes.

My amp is also labeled 'Tech Instruments, Woodside, NY'.

I will try to upload some more stuff in the near future.
I also have copies of reviews, a company leaflet, etc.

I found the biasing instructions somewhat confusing-
I have not actually done it yet. This is not an ST-70!

Here's my schematic with some crossouts/changes as
found with my amp.

Thanks, Clay
