something my friend is working on.
RF deck is about done he needs to finish the power supply.

I wonder how he is going to balance the pair of GS-35Bs. The problem with these tubes s they don't play well together. To be fair, on CB it probably doesn't matter since linearity is not at the top of the food chain.

Not like this where the tubes are wired together in parallel on the same winding:

He needs to run separate filament windings for each tube, more like this:

I don't see a connection for the B+ to the Tube anodes nor, do I see a tank coil between the Vacuum Variable and the Air Variable on the bottom.

PROBLEM: The filament voltage as well as the RF input is situated on the "Top" part of the RF deck along with high voltage and the Kilo-watt output.

I wonder where he's gonna put his antenna switch relay?

Does it have input tuning for those cathodes?

I wonder if this thing ever made it off the work bench; it's pretty on the outsde but a design nightmare on the inside.

1. That thing needs a Vacuum relay to handle the antenna switch.

2. And, it also needs a fixed Vacuum Cap to use as DC Blocking; those surplus(?) green will not hold up over time.

3. What's up with installing the forced air cooling blower INSIDE the cabinet? It's only going to suck in is Ozone that has been created-superheated by 6000 input watts!

4. He should have used a Vacuum Variable for his output also.

6. The 6000 watt output is in very close proximy with everything associted with the input.

Show us some updated pics on that thing!
