I running the Aric Audio 6SN7 Linestage/preamp in front of the SET amplifiers. This is my second linestage from Aric — I sold the first one and missed it so much that I bought this one. An outstanding linestage preamp running my all-time favorite tube, the 6SN7.
The USAF 596 rectifier is a 5U4G equivalent – it was developed to operate in high altitude aircraft without internal arcing. The 6F8G is a 6SN7 equivalent with external grid. As seen in the photo, both require an adapter to accomodate the external connections.
