Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

General:
This listing is for 10 total vacuum tubes. The 8 that have open boxes have been tested and are running strong, and the other two are new old stock.  Perfect for completing an amplifier with period correct tubes.

The PCC88 tube, also known as a 7DJ8 shares the same internal construction as a 6DJ8 but has a slightly higher filament voltage of 7V rather than the more typical 6.3V. The Siemens PCC88 is often substituted in 6DJ8 or 6922 positions.

These tubes have Siemens markings but all but one have been branded Telefunken.

SkyFi Cosmetic Notes:
Boxes show some wear, good condition overall.
