Here we have a homebrew TX just finished:
Geloso VFO 4/102 and dial scale
Geloso modulation transformer 6055
Geloso PI coil
Geloso 1500pF Load variable capacitor
VFO adopts 6J5, 6AH6, 6L6.
QB3/200 Rf power tube 1.2kV anode voltage, 130 mA typical anode current.
Tubes in the modulator are 12ax7, 5687WA, 2 * 6KM6 audio power tubes 600 V anode voltage.
There are semiconductor diodes in the power supply and a voltage regulator IC for the relais, the fan and the panel lamp.
There is my anti overmodulation circuit. (see here
http://www.ing.unitn.it/~fontana/AM%20ALC.pdf and look for updates).
Four meters: Ig, Ia, RF, %mod.
Relatively compact design
100 W carrier out
Six fuses (most important...)
