I just bought a cool preamp (hand built by a Romanian gentleman) that uses 101D tubes. I purchased it second hand and the seller included a pair of tennis ball 101Ds unbranded, black base that sound very good except for the fact that one tube is noisy. The 2nd pair he included is a pair of PSVane 101D-Ls that are just OK. Does anyone have any recommendations (I need the longer pins two fat/two thin) and/or any 101Ds they're looking to sell?
I would try and bite the bullet and get some WE 101D or F (if they work with your amp). ST is most likely what you will find. Check some Japanese websites as they seem to have a lot there. I got mine from Japan at way lower prices than I found here or on ebay. A nice UV4 to UX4 converter will solve any pin issues.
If you are looking for new production, I would check out linlai. They made both a mesh and solid plate 101d in ux4 pin layout.
