[Amps] New Guy, Old 813 amp

I guess that is a big option, at the moment. I think I need to learn how to build tank circuits, as I am trying to figure out how to add 10 meters to it, but the 813 GG circuits I have seen are not helping me much for uH requirements on the coil taps...

Great challenge, but I hate being a new guy...

Thanks,

Scott

The biggest problem is mechanical, like mounting a switch in 
the amp. It's pretty easy to handle the rest.

I think you are asking for more problems by using a 
transplant because none of the component values will be 
correct and the mounting aspects might be worse.

Why not find a switch and then build around it? There isn't 
any law the switch has to be ganged to the tank switch.
