Hi all, Im new here and was wondering if someone could help me identify a valve with no markings, The amp it comes from is an integrated 211 Push Pull output handmade for production but never made it to market. I have no circuit drawings at all.
 
Hi Dan, Here are some pics, between the 4 x 211 are 2 x ECC82 and behind them 2 x Unidentified, They seem to be drivers for the 211's (but i,m no expert ) 9 pin base (same as the ECC82) same diameter tube, 69mm high from the bottom of the glass base to the pointy glass tip. The only marks i can see are: VB9 and 45J3
