Presumably you mean Parmeko, who were well known for their high quality transformers. I didn't know they made amplifiers too. The company survived until 2014: https://www.thegazette.co.uk/notice/2109991
I don't know the circuit but if there are any capacitors coupling to the output valves these need to be checked and probably changed. Even a small leakage here can damage the output valves and transformer.
