[R-390] 6082 another question

[John KA1XC]

Yup, that would work well Dave. Unfortunately the 390 is so crammed with
modules that there's not much room left inside.
But there is some room behind the front panel, so if you had a compact
enough transformer and were clever with some mounting hardware it might be
possible to attach it to the X-frame between the KC and MC shafts.

Another no-holes 6080 mod which I've thought of is to mount them on a small
outboard chassis along with their own filament transformer, and connect them
back to the audio deck via the side vent hole with a foot or two of cable
and an 8 pin octal plug (just need one plug and it moves all the heat
outside the radio). It's really the same thing as tube socket adapter except
that it's outboard because of the space requirements.

Before anyone dismisses this as too bizzare take a look at the CV-157, it's
got seven tubes (including a 6080) in a seperate power supply tube chassis
which is then connected to the main chassis below via a cable. I just wish
they would have connectorized it as it would make servicing easier.
