I have a stash of tubes , more than half of 'em I can't remember where they came from. Decided to take some time this morning and test them the old-fashioned way - since they were mostly 12AX7's , stick 'em in V1 of the Maz 8 and fire away! Unscientific maybe , but of 6 I tried , 5 are headed for the bin. Whistling , squealing microphonic. Shuguang 12AX7B's , Sovtek 12AX7WCBs and a Groove Tubes 12AX7-R ( which is a Sovtek 12AX7WC). Oh well , good to clean out the drawer.
