New Tubes for my Drawmer 1960 reccomendations

Just looking for some new tubes for my Drawmer 1960. Contacted Drawmer tech support and they said since my unit is 20 years old the tubes could may well be the issue im having with it.

Any reccomendations to a sweet sounding (not overly distorted tube). The unit uses 2 AX7 and 2 AU7.

Cheers!

JJ tubes are pretty nice. I’ve not heard the new Mullard ones, but I bet they are good too. I need to replace the tubes in my Thermionic Culture Phoenix and am thinking about trying the Mullards.

Lovely, ill check them out. Thanks for taking the time out to reply.
