i stuck some used mullards in my amp a few months ago.
anyway, i mentioned this to my old man, thinking he might be interested as hes an electronic engineer too. he goes to me, i think my pal ken has some old valves, and he worked for mullard for a while.
he went to see him recently and picked up four ECC83 mullards as a present - two of them are unused military spec ones. the old man posted them and they arrived this morning, can't wait to try them. my marshall jmp50 already sounds well tasty with the standard mullard used tubes.
spring has started, and this is marvellous good fortune. i reckon a nice present for my old man's mate is in order!
