Everything is in bound. I found the relays and made an offer on the trimmers and the seller accepted.? Going to have 125 bucks or so into this.? Will probably need some mica caps also. I have some, Fred sent some. We will see.??
Should be able to start the build next week.?
This will be interesting.? I took drive power/output power/IMD/GAIN/ efficiency plots of the amplifier without the input.? Let's see what the fly wheel effect does back-to-back.
I do need to order some micro switches.? On this amp there is no 10-meter 24-volt signal. The 10/15 share a band position.? It uses a roller.? I will need to mount the micro switch to the roller or drive system to click in the 10 meter input and drop the 15-meter
input when the roller gets past 15 one its way to 10 meters.

I see a quantity on Ebay but they are a small fortune. Not what I expected.

I found the relays and have ordered them.??
I can't find the trimmers.? I need eight 30-300PF and two 100 to 700pf trimmers.? No data on what they are or voltage ratings.? Any idea?? Arco?
