Howdy all and Happy New Year,
OK, got a question for some of you seasoned amp builders. I am at long
last beginning the rebuild of my 4-1000 amp. To refresh your memory, I
am having to deal with the housing and mechanics of someone else's
design. The old tank circuit design was not at all stable and as I have
discovered, the C-load was not the correct value either.
The C-tune is a Jennings vacuum variable and it mounts above the C-load.
I spent yesterday building a bracket for the C-tune but realized today
that the bracket interferes with the plates of C-load. C-load is mounted
on the floor of the amp cabinet and as the knob is turned the plates
rotate upward (z-axis) and reach a maximum height at half capacitance.
This is when my problem occurs.
I have an idea for changing the bracket design so as to eliminate the
interference. However, part of it still will come within about 0.25" to
0.5" of C-load's plates when the height of the plates are at their
maximum height.
My question is: Is this too close for metal to be coming near the plates
or is it OK? I don't want any surprises when I power the thing up.
Thanks es 73,
Jon
