RE: [TCML] Tiny VTTC

[William Noble <william_b_noble@xxxxxxx>]

it seems to me that in about 1964, popular electronics had a plan for lil-TC and Big-TC - and the little one used a 6V6 - that woudl be a good place to start - I scanned the article some years back and sent it out to those who wanted it
