Hello to the group!
I'm slowly moving forward on my 2 amplifier projects. I'm in the information
and parts gathering stage.
Amplifier #1
Single GS-35B for 6-meters
Amplifier #2
Dual GS-35B for HF
(both amps will use W4ZT's awesome sockets!)

I believe I've read on here before where some owners have built MONO band amps
but powered them all from a single power supply. So I thought, "Why not design
a single power supply, capable of supplying a pair of GS-35Bs easily, and have
it power a single GS-35B also." I should actually SAVE money over building two
separate power supplies, although this project will be a little more expensive
than building just one.
So, one power supply deck and TWO RF decks. It has been suggested that I use
vacuum relays to switch between the two RF decks. I was hoping to have them
both run in standby at the same time. I obviously do not know enough and am
therefore here seeking guidance. I will only operate one amp at a time.
One of the big expenses is the power supply transformers. I am aware of Peter
Dahl and MagCap. Are there any other suggestions for transformer
manufacturers? I understand that Henry had his transformers made in Los
Angeles. I was going to call him today.
I'm working on getting the required specs to order the appropriate
transformers. I am also looking for any input this group may have.
Second question, how do I determine what blower to buy? I would think that all
I need is a CFM requirement for the tubes and buy the appropriate blower. I'm
finding that its not this simple. I was thinking that a larger blower with a
lower RPM will be quieter. I have given thought to building a blower enclosure
and insulate it to help keep the noise down. Where should I start looking for
blowers and what advise could you give me?
I plan on documenting this project as I move along. I'm working on getting
some web space to post pictures and commentary.
Thanks for ANY advise you can give me!!!
