i intended to use WE 101D's all along. however, i did not know that they were incompatible with the sockets used by the tj 101d's. we 101d's use uv-4 sockets. they are hard to find and normally expensive when you do. there are a very few current production uv-4 sockets. some of the best are pulls from old western electric amps. i supplied Mick with the sockets that are used in my cabernet. these sockets normally sell for $200-300 ea on ebay. but i managed to picked up some old WE bakelite sockets in excellent condition from a local tube collector.
i have never listened to the tj 101d's but by reputation the we 101d's are said to be superior. the tj's are based upon the WE tubes. the WE 101D's were manufactured under license in Canada, Australia, and I believe the UK also. So there are a few working substitutes to be had. I know in Australia they were manufactured as the STC 4101D. There are a few other variant model numbers as well but they are all basically the same tube.
there are a very few interesting posts on AA by Dowdy Lama and Gordon Rankin regarding the WE 101D and TJ 101D. Search through all forums.
