great work.
the bulk of the ceramic xtal socket shold be below chassis, with only the raised part (where the xtal legs plug in) protruding through the chassis.
Thanks. I am aware of that, but for some reason some of the ARRL projects from this era showed the sockets mounted above chassis. Call me strange, but I'm actually trying to make the TX look as close to the original design as possible, even down to odd details like that one. (And of course, the XTAL socket will work alright, either way.)
Other strange things I am doing: using exactly the same sockets even though they would be considered non-standard nowadays. So, for instance, the telegraph key socket is a phono socket (not a 1/4" jack socket); and the antenna is also a phono (not a UHF connector). The high-impedance headphones plug into the sidetone oscillator using those ancient connectors called "tip jacks."
I am making only two exceptions to the rule of "historical accuracy":
(1) If my components aren't the same form factor as the original ones, I am making slight adjustments to the positioning, such as when I moved V1 slightly to the right in order to avoid the tube being too close to the power transformer.
(2) Safety. I am using a three-wire AC cord and putting an IEC receptacle on the back panel along with a chassis-mounted fuse on the Live side of the circuit, and grounding the chassis to mains ground. (The original design has two-wire "lamp cord" and a double-fuse system because the plug was unpolarized.) Historical accuracy is all very good, but it's trumped by Stayin' Alive!
This transmitter, and its companion receiver that I built last year, are basically a "one-off" exercise designed to replicate the station that I wanted to build as a 12-year-old, but never did. Once I've got that out of my system, my designs will become more personal and not hew strictly to ARRL designs!
