Report Review for product Vacuum Tube - 11BM8, Triode, Pentode

Too bad this vacuum tube is not manufactured anymore. Seems to have quite a bit of availability despite their age. I have 4 of these tubes in an amplifier where each channel uses two of the 11BM8's. Very nice having a triode for pre-amp and pentode for power amp purposes. Sound is good in the mid ranges on these tubes properly configured in an amp circuit.
