Does anyone have/know of an index for NZART's Break-In magazine for around the 1968 to 1972 period?
Back around that time I built a 2m AM transmitter that used a 5763 as the output valve and possibly an EF86 as the mike preamp valve.
The xtal oscillator/doubler was possibly a 12AT7 with the whole thing, from memory, consisting of 4 valves in total not including the power supply.
I would like to find out if it was possibly published in Break-In and get a copy of the circuit or even the article.
There used to be a link to an index on the NZART site but all that does now is go "naughty boy, not allowed in here", otherwise known as a 403 error.
I do have a circuit that was in a US book and while close, something is niggling at me that it is not quite correct in terms of the one I actually built (it uses a 6AB4 triode as the mike pre-amp).
