These were manufactured right after the Large Black Plate (LBP) type during the mid-late 1950's. Construction wise they are identical to the LBP but with gray plates. And, sonically you can expect something between LBP and Clear Tops which is a later version : Less creamy than the LBP and less bright than the Clear Tops.

Grade A -
The best in the stock. Lowest noise and microphony with the tightest balanced
sections we have available. This is typically 10% or often tighter given the
large volumes of our stock.
Grade B -
Low noise and microphonics with a section balance typically between 15% and 20%,
but may be higher depending on available stock.
Grade C -
Lowest noise but slightly microphonic. Section balance will be similar to Grade
A or B. This grade is only suitable for use in the driver stage of an
amplifier, or the output/buffer stage of a DAC or CD
Player.

ReplyDeleteReally nice sounding tube! As described, if you want something in-between the RCA Clear Top and Black Plate this is the tube. It is both clear and warm, bright yet smooth.
