CF2 miniature pentode/triode input valves were indistinguishable from
Mullard EC82 (?) replacements; Shuguan EL34 and various Chinese 300B
output valves all worked and sounded perfectly fine - including Golden
Dragons branded 'Audio Note' and 'Chelmer'!
Streuth, that reminds me it's Christmas time again - here's a pic of my
miniatures off on their Christmas Holidays a few years ago!

And I'm wondering now if I didn't have a Chinese rectifier valve go pop on
me....??
