blast from the past! sadly long gone

Thanks! What a large complex, almost hard to imagine it's gone. What a shame.

Yeah it's a good film,mullard got it right for quality,i never realised how much work went into making a valve! i have a mullard ecc83 from the 1960's in my lite2 preamp and it sounds great and still tests good for emission's!
