For sale a 6B8G double diode pentode IF/AF amplifier / detector / AGC valve / vacuum tube by Tungsram, new in original generic white box. The 6B8G pentode has a semi vari mu characteristic, making it ideal for both AF amplification following the detector diode, or as a final IF amplifier with AGC applied before the detector.

This valve is brand new old stock and in pristine clean condition with all original markings present and correct. Recently tested at 100% of nominal new emission on all three sections.

Of particular interest to radio set restorers, collectors and experimenters alike.

Why risk 99p (and the postage cost) on an untested, used valve when you can still get guaranteed new ones (or your money back) from Helmore & Hunt?
