Probably the most popular power pentode tube... The oldest production of Tesla, made in Czechoslovakia.  These have single "O" getter, welded plates and brown base, and were made with Philips tooling as a good copy of the famous Mullard xF2 line. A rare version and very hard to find in true NOS condition like these. No label imprinted on the tubes since these were imported for gov't & military use to the West during those early cold-war days.

BRIMAR CV133 / L77 / EC90 / 6C4

 BRIMAR CV133 / L77 / EC90 / 6C4

The 6C4 is a miniature, medium-mu triode approximately similar to one section of 12AU7. It is useful as a local oscillator in high frequency circuits and as a power amp in RF circuits. It is a common tube in Conrad Johnson and some Heathkit amps. These Brimar tubes have black box plates.

Quantity in Stock : 65 pcs
Price : US$ 15.00/each ; US$ 32.00/matched pair   

Telefunken/Philips/Siemens/Valvo E80CC

Telefunken/Philips/Siemens/Valvo E80CC 
A ruggedized double triode of frame grid construction introduced in 1957. This type was manufactured only in Holland by Philips/Amperex and in Hungary by Tungsram. Technically it is similar to ECC82/12AU7 with slightly different operating parameters and double the filament current requirements. It is nowadays a popular replacement for 12AU7 as long as its EL84-like size and power transformer capacity allows. The E80CC is my personal favorite 12AU7. These tubes have halo getter and gold pins, and sound like a Telefunken ECC802S on steroids that means an absolute audiophile hi-end!! Strongly recommended! The Holland tubes in stock have various labels such as Siemens, Philips, Philips Miniwatt, Telefunken, Valvo and Teonex. These come screened for noise and microphonics.
Quantity : 25 pcs
Price : US$ 75.00/each ; US$ 155.00/matched pair
