Murphy a252 vhf question

[Mike76]

I've got it plugged into an external one so it's good. The effect of increased volume is had with the lightest touch with anything metal on the capacitor leg and seems most pronounced wit it grounded to the chassis through another capacitor. I need to get my signal generator working and align everything properly as I just tweaked it all without it until I got the best reception. I've no idea where it is on the scale as it's not attached to the chassis at the moment.  I'm just glad it's working really.  I am just learning and went about it the wrong way really.  I think I should have started by trying to align it first and seen where that got me, that way I guess it would have pointed me towards any problem areas. That and checking all the voltages at the valve bases. You live and learn.
Thanks for your suggestions,

Mike
