2A3. Posted by Donald North (M) on May 26, 2007 at 12:57:48 . When I look at the construction and plate structure of the Sovtek 2A3 and Shuguang 2A3C, both resemble a 300B, just smaller. Using the original monoplate RCA as a reference, neither tube is constructed like it with the rectangular plates being supported along their left/right edges.

- 2A3 tubes measure fine - Noise was constant when tube was new, seller suspected small flake of debris on something inside, recommended firm (but not too firm) taps of glass against a table and then a few more solid taps but with the base against the table. Repeat 1 or 2 more times if needed (I did).
