Wow,

What a wonderful story! I was fortunate to be at a school with a very strong Radio Society, which got me started, Amatuer license at 14! Been in Electronics all me life, but got back into Valves 12 year ago, and now it is my business, even one day hoping to make some money!!
My first Amp was the Mullard ECL86 as well..
Those were the days..Believe me you have no wish to guess the price of a UK wound output transformer! But that is what I use for my own designs, that are actually selling ok!
Lastly, I made a stereo headphone amplifer, as a challenge for a Hifi show, using a pair of Lucas Ignition coils! I cut them open drained them, then separated the primary and secondary windings, added 4th wire. Glued back together sans oil and ran them back to front.. Astonishing result..Using at EL36 on each channel and a couple of 12AU7, nearly a watt!
Fitted with a car key switch to turn it on! Bonkers..
