I bought them on eBay from the seller Planetj60847.
Listing: 2C51 LM Ericsson
I have the steel pin version but supposedly the gold pins are even better with an even black background. I've been searching for awhile now and they are hard to find.
Thanks bro!
Been a while, just checkin' in on what you crazy tube warriors are up to. I feel it is my responsibility to point out that this was the seller who kept increasing the price on the LM Ericssons when no one was bidding. I believe he was Black Listed lol
