wiring diagrams

 

(Updated drawings, minor corrections.)




(More corrections:  Electrolytics are 22uF @ 50V, not 25uF.  Decoupling caps are 22nF @ 630V, not 20nF.  In cathode circuit of phase inverter, it's a 5.6k resistor, not 5.8k.  Also, note that in my actual layout of the two circuit boards, I have placed all of the HV power supply components (2 x 10uF electrolytics and 2 x 10k @ 2W resistors) in one group at the right end of board #1.  Finally, there is an additional 100k LED resistor next to the two shown, on the left end of board #1, and there is a 10M LED resistor next to the HV supply components on the right end of board #1.  These are for the RGB pilot LED (red = +15V, blue = HV).)

(Still more corrections:  The two 220k resistors associated with the phase inverter, need to be grounded at the node where they connect together.  And the two 0.1uF caps connected to these resistors need to be rated for high voltage (630V being my standard throughout the circuit, though 450V would probably suffice here).  The 33n cap associated with the presence control, shown as a "flying component" in the diagram, is now mounted on board #2.)
 
(Further corrections:  The sense of the presence knob wiring needs to be reversed: i.e., clockwise decreases resistance; opposite of the depth (resonance) knob.)

final interconnection, first power test

Connecting the new circuitry to the VTX chassis.  Most connections are through the 12-position "Euro" terminal strip, except heater power (to the left) which is hard-wired. First power-up, with no tubes inserted.  LEDs ahoy!  This just verifies that the +15V power supply is working, and I haven't made any grievious errors in the wiring. I verified that the channel-select 3-way switch works, turning on and off the yellow and green LEDs on the VTX, and the preamp-select 3-way works, turning on and off the white LEDs (yes, those are white, not blue as they appear in the camera). And I verified that the HV supply works, by taking it out of standby and observing that the blue LED of the RGB pilot light illuminates.  (It's a bit dim with the 10M resistor though, I guess I need to decrease the resistance; gotta take care with the power dissipation...)

schematics of my mods

  Again, caveats from the previous post apply here as well.  Most significantly, I have not yet built the boost circuit, nor even verified whether the VTX power transformer can handle the additional heater current load.  And some of the wiring of the phase inverter, vis a vis nfb, has not yet been implemented or tested.  So these circuits are to some extent, aspirational.
