Hi All,
I'm rebuilding my Wurlitzer amplifier and it takes 2 7199's.
They have been very illusive thus far so I thought I'd ask the good people here if there are any spares to be had. I need 2 but I'd take 4 if available (just in case). I'm not looking for cheap, just fair prices would be appreciated.
Many Thanks, Mauro

They have become rather expensive, especially NOS US manufactured.
I tried some Russian ones but the dozen I purchased (6 from one source and 6 from a different source) all caused low level hum from the speaker. Those purchases were about ten years ago. Perhaps they’re better now.

These days it’s quite common to use a 6AN8 to replace hard-to-find and often over priced 7199’s.
NOS 6AN8’s of US manufacture are quite inexpensive and widely available.
Use of a 6AN8 requires some minor rewiring of the socket.
It’s a very popular way to replace the 7199’s in the Dynaco ST-70 amp. In the Dynaco mod one must cut a couple of traces on the circuit board and install a couple of jumper wires in order to accommodate the slight difference in the pin outs of the 6AN8 and 7199.
If your Wurlitzer is wired point to point it’s even easier.
I’m sure you can find the modification on the WWW. If you’re unable to do so, let me know and I’ll provide you with instructions.
