Default the valve with no markings

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.

How about posting some pictures. Unless you are talking about one of the 211's then we don't have much to go on.

Default Try heavy breathing.....

Find some good light (like next to a window) and breathe on the tube, the condensation from your breath may show some markings.

I think it might be an EL84.








BTW this is a guess
PHOTOS or no one gets it...

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
