Thanks Carl... I will use the 80m core design as the baseline.
What I need is a target inductance for the 160m core. I think a turns
count from the 160m core on an early model 70 or 77 series amp from Alpha
would get me close.
Does anyone happen to have a PA-70/V or 77 series amp that can tell me
their turns count on the 160m tank coil?
Thanks...
Mike K9MK

I would think the toroids and the coil is the same since the 3 tubes are
similar and on 160 nothing is that critical. The toroid itself is likely a
Micrometals #2 mix. Go to Amidon and get one of the same size, use Scotch 27
tape and Teflon wire.
