You folks started it.
I was hunting thru the trailer today and found a pair of the 9 pin loctals; EPF60's.
Amperex mfg. One with black lettering and one with (probably ) yellow or maybe orange lettering.
Not only that, but the pins have pretty SHARP points on the bottom. (DON"T ASK
They are not listed in Tube Lore, nor update # 3.
I'll email Lud & see what he can tell me on these, and post it here, unless Norm or another member has the info.
Having problems trying to post pix on this one
