I would like to try the Telefunken DL92 tubes with my quickie. Does anyone know where I might find them for purchase? I have done some googling and checked ebay and they don’t seem to be easily available. Thanks.
They come up on eBay from time to time, but don't pay over the norm for them as they aren't anything special. There also seems to be a couple of variants of them with grey plates and shiny plates. My preference are Philips made tubes, which also got sold under a bunch of different brand names, just search for DL92 instead of 3S4.
Thanks for the suggestions. I live in the US and was hoping to not have to order them from overseas. I was also hoping someone here had a couple extra to sell. I've had the RCAs running for a while and wanted to try something new.
I bought a pair of DL92 Siemens from https://www.tubesandmore.com/search/node/DL92 that are made in West Germany. They seem to be a little less microphonic and a little more dynamic than my Telefunken's. They are located in Mesa, Arizona (Phoenix metro). You might want to give them a call and see what they have.
