Oops soz I meant to add a pic sorry its a bit naff.
I dotn know if the xtal is series cut or parallel, I tried a rc 27.125mc xtal, and a 4.43 colourburst, the socket is not a hc49, its one of those great big old doofers (the socket centre right, you can just see the 4.43 xtal on top of the machine), neither the 27mc or the 4.43 change anything on the 'scope or counter.
The 27mc xtal is a third overtone, and the 4.43 is a fundamental, if the 27mc one gave me 9mc fundamental at least the thing would be working.
I'll try squirting the sw with some servisol, its never been on the xtal psoition since I've had the thing.
