[Boatanchors] BUD Tunable Lowpass Filter - Looking for info

[Glen Zook]

I believe that the BUD low pass is pretty much the
same as was described in the ARRL Radio Amateur's
Handbook back in the early to mid 1950s.  That should
be a good place to start.

Also, I have one around somewhere that I have never
tried to tune.

It's a BUD Low Pass Fliter model LF 601A About a foot
long, it's unusual in that it seems to be a tunable
LPF, not fixed. 5 stages and 5 variable capacitors for
screwdriver adjustment from the outside. Havn't seen
this one before. Does anyone have spec's on it?
