Looks great. I like the drives for the caps mounted vertically.? Neat idea.?

How much are those Type 90 switches?? ?I recognize it.? I have one inside my outdoor antenna switch.? Its stepper driven. I can't remember who made the switch and console. I got it at a ham fest many years ago.?

I would think a nice kintronics Roller would just be easier for this. But I am sure it will actually work better band switched. The coils can be optimized for each band.

I know you guys like those triodes, but I would put a 4cx5000 in that amp in a heartbeat.

?
Ceramic Vac tune and load caps? mounted vertically, both with right angle drives below chassis.? ?Between the front panel and sub front panel, they will both feed a sprocket assy, so the actual turns counters will be above the chassis.? Multi-tech industries Model 90 bandswitch has been modified, such that there is now 40 amp contacts on both sides of the single wafer. Contacts on both sides to be strapped in parallel. There is a pair of multiple pole rotor assy's, (aka progressively shorting type bandswitch).

Neither vac cap has to be padded on 160M.
