Jey over in SET Forum just posted this for another message.
I remember this article: it is a Product Review, and published complete curves, and a sampling for consistency, and the consistency was fairly good. This was 8/01: things change, especially in the sovyet tube business. Ask Victor K if he thinks this data could still be trusted. or ask Sovtek for newer data.Here's data from AudioXpress 8/01 Product Review of Sovtek 2A3 Platinum Matched Tubes.
Comparison of 2A3 plate currents @ Vak= 250VDC, Vg= -48VDCSample 1
IP(mA RMS) 27.7, Gm(mA/V) 6.34, u 6.49, Rp 1.02K, P 6.94W
Sample 2
IP 29.2, Gm 6.03, u 6.34, Rp 1.05K, P 7.33W
Been using Sovtek 2A3's in my Fi-Primer Loftin White for over a year.
Hope this helps?
