Electro-Harmonix 2A3 EH Gold Grid | Wonderful, smooth sounding!


About 10 years ago I was able to purchase a pair of Welborne Labs Moondogs. I am the fourth owner of these wonderful amps, and the seller inclided a pair of Sovteks and the EH-2A3. The Electro-Harmonix tubes are more balanced and smooth, and work very well it these amplifiers. I swap between powering Klipsch LaScalas and Klipsch Heresy IIs.

Never had the money to buy more exotic or NOS tubes, and will be buying more of these for backups.
