Sinclair mtv1

[timmy]

Ok so I’m back with this little tv I got varicap diodes that are known to work in this tv but still cannot get it to tune so is there a way to tell if the rf amp is working along with the oscillator and mixer without a scope. The voltages on all 3 transistors all seem to be the same I don’t have anything that tells me what voltages should be this is a tough one but I have to look at this as if I have no info on it. Any help on this issue will be appreciated.
