Hi everyone - good news! This Zenith set now goes , and goes really well.I have replaced all the wax paper capacitors , some of which were original Zenith ones and the rest ones that had been replaced earlier.Several resistors had gone high as well.Once the bias on the 6F6 was put right the tone improved pleasingly too. At this stage it seems sensitive and not in need of any urgent realigning - so smiles all round and something to take to our Zenith themed meeting this Thursday.Thanks for your interest everyone , and an especial shout out to Madsowry for pointing me to the model and schematic , and for his genuine Kiwi greeting !
