Without an elmer, I thought I would ask a question here. Maybe someone has an idea or explanation.
Recently while researching my next project rig, I was looking through the many great regen RX designs and observations of N1TEV.
Along the way I also ran into a few tube type plans as well as even a couple of matching tube transmitter plans and was quickly smitten with the simple tube rig construction articles (Of which I have absolutely no experience at all, age 45 here).
So trying to put the final selection on a pair of designs, I figured the availability of components would make the decision for me - but for some reason I have not given up yet
Seems the hardest part to even figure out what I need let alone find it are the power transformers for the RX and TX on these 1960's designs with which I am so intrigued.
The Allied P/N's do me no good anymore, but in the TX plans it says "Secondary: 125v @ 50ma, 6.3v @2A". This appears to be the higher rated tranfsormer of the RX and TX.
It does not list a primary voltage (?) but shows it connected to 117VAC on the primary side. After looking at alot of designs - some are inevitably from other than the US and 'mains' supplys can be different.
Looking online at a few various sources so far I have become even more confused.
Some vendors list the primary voltage and a CT voltage but NO secondary voltage? How can one buy a transformer and not even know the secondary(s) voltage(s)? Do I just double the CT value?
Even the plans as written above say "Secondary", as in singular, but then list specs for 2 windings?
Am I missing somthing or making a mountain out of a mole hill?
I knew I would learn somthing trying a tube project (Or two). Thats part of the fun.
I just did not expect to be so confused so fast, especially by just the power supply. Whats old is all new to me.
Before proceeding with a tube design I need to be comfortable with the supply as I know these things can bite.
