Hi Len!Where've you been? Been missing seeing you around. Whatcha been up to?
The Valve Art 2A3's are inexpensive, which I think is why they're the standard tube in entry level kits. But the blue halo is nice, glowing like a flame that gently dances to the music. That alone makes it worth buying a few to find a pair that don't pop.
As a replacement for Valve Art's, I think I'll try Electro-Harmonix 2A3 tubes in my Paramours. Maybe try Sovtek tubes sometime too. And one of these times, I want to swap out the transformers for better Magnequest iron and then move up to an RCA or Tung-Sol 2A3. Probably nice to build another pair of amps, so I can compare the stock build with the improved one.
What do you like about the 300B as opposed to the 2A3? Do you suggest changing bias to run a 300B in Paramours?
