I have a Cayin amp that uses 6N6 tubes - does anyone know of a decent NOS replacement/upgrade tube I could use?
Hi, I found this thru google:
6N6 (chinese), 6N6P (russian). This tube has NO known direct replacement: the best replacement is another 6N6 - 6N6P. However if you are experienced, and with the proper tools, it could be replaced (given socket rewiring and maybe some circuit tweaks) with 5687, 12BH7, ECC99 or E182CC. This last tube seems to be the closest equivalent.
