So please ASK for the shipping possibilities to your country. ----------------------------------------------------------------------------------------------------------------------------------- Original vintage tubes. Made by Siemens in Munich, West Germany. Made for PROFESSIONAL use. Made for professional audio equipment like Klangfilm V203, V204, V402 and V403 cinema amplifiers or Telefunken V69 / a studio amplifier. With METAL base and o getter. See pictures. KL. 73551 is the professional version of EL12. Other name is F2a11. Equivalent to F2a Post tube - but with a different base. One of the BEST audio power tubes ever made! Old stock. Tested on Funke W19 S military tester with VERY GOOD results: both tubes measure around 54. Good tube starts at 32. EXCELLENT audio tubes. Hard to find now!Your bid is for TWO (2) tubes. (32 06 17 1) Watch our other auctions, too. A lot of rare German and European audio tubes available! International shipment (registered airmail): 30 USD. We ship worldwide and combine items. You can combine all items sold in any currency - we will convert the total amount and the shipping costs in one currency. Please ask for prices in case of combined shipping.

For sale is a matched pair of the very rare and highly wanted vintage output transformers type BV 7105/2. These transformers are interleaved - both secondary coils are connected parallelly already. This connection makes the frequency response from 30 Hz to 18 kHz.These output transformers are perfect applicable for SE power stages with aAD1, ED, RE604, EL12, AL5/EL5, F2a11, or other tubes, with output impedance in the area between 2,2 kOhm to 5 kOhm. The max. power capacity is ca. 8-10 Watt and the ratio is 1:18. With the ratio about 1:18 these output transformers are suitable for following application: For Example: AD1/ ED Single End - 5 Watt, (U supply 300V, Ua 250 V, Grid -45 V,cathode resistor 750 Ohm) Ra 2,3 kOhm - usable output impedance 6-8 Ohm respectively with RE604 with changing the cathode resistor of 1000 Ohm RE 604 Single End - 2-3 Watt (U supply 300V, Ua 250 V, Grid -45V, cathode resistor 1000 Ohm) Ra 3,5 - 3,8 kOhm - usable output impedance 8-12 OhmOther solution with the BV 7105: EL12 / EL6 Single End - 8,2 Watt (Ua 250 V, Screen 250 V, Grid -7 V) Ra 4 - 5 kOhm - output impedance 12-15 Ohm (this was the original application) EL5 / AL5 Single End - 8,5 Watt (Ua 250V, Screen 275 V, Grid -14 V) Ra 4 - 5 kOhm - output impedance 12-15 Ohm F2A / F2a11 Single End - 10 Watt, (Ua 250 V, Screen 250 V, Grid -7 V- as in Klangfilm Kl. V204) Ra 2,2 - 2,4 kOhm - usable output impedance 6-8 Ohm The normal output transformers constructed for PP power stages, and as well so called match transformers for adaptation of low impedance speakers for high impedance amplifier outputs, are not suitable for using with a SE power stage!! The iron core for OPT in a SE power stage must be assembled with so called magnet slit For creation of a magnet slit all iron sheets must be interposed in one direction only. Therefore the BV 7105 are perfectly suitable for application of the RE604respectively AD1, or for each other power triode or pentode with Ra output resistance about2,2 - 5 kOhm. -------------------------------------------------------------------------- The weight of each transformer is 1,4 kg. The total weight incl. package is ca. 4 kg Shipping is possible as a DHL Standard packet up to 5 kg.

Röhre Siemens EL12/325. Gebraucht, aber noch sehr gute Werte: getestet auf dem Röhrentester Vakkum gut, Ia = 36 von nominal 46 mA, S = 11,2 von 11 mA! Sockel wackelt minimal, hält aber gut. Used, but still very good values measured on tube tester! Good vacuum, Anode current 36 mA of 46 mA (according to specs), S = 11,2 of 11 mA/V! Socket slightly loose, but still holds well. Will ship internationally. (Internal Ref.: 4)
