Beschrijving
Almarro 318B Single Ended 6c33b/c buizenversterker.
Zelden aangeboden.
Niemand in het westen had gehoord van de 6C33b buis, totdat in 1976 een Russische piloot overliep en zijn Mig 25 in Hokkaido in Japan aan de grond zette. Verhaal staat onderaan deze advertentie.
Deze Almarro speelt heerlijk en is optisch en technisch in prima staat. Onlangs geserviced en voorzien van enkele nieuwe condensatoren.
Gebruikte buizen 2x 6c33b 1x 6SL7 en 1x 6SN7.
Vermogen 18 watt Single ended in Klasse A.
3 Line ingangen.
De 6c33b buis gaat “slechts” 750-1000 uur mee.
U denkt, dat gaat in de papieren lopen. Dat valt reuze mee want je krijgt er +/- 16 stuks nieuwe NOS (Ulyanovsk) bij. Sovtek maakt de buis nog steeds.
Versterker kan niet verzonden worden, want geen doos en het forse gewicht.
Uitgebreide Manual is wel aanwezig. Valt uiteraard te beluisteren.

In 1976 a Mig 25 fighter jet landed in Hokkaido in Japan, it was flown by a soviet military pilot that wanted to defect to the west. This was a real field day for western miltary people as not so much was known about the MIG 25 and the plane was completely dismantled.
Two things startled the military analysts in the west, the first was that the plane was built using a lot of high tension steel, it was earlier thought that the MIG 25 was built in Titanium to withstand the heat that is generated by flying at mach 3 that the plane was capable of, that it was built in steel made it heavy so the performance was actually less than expected.
The second thing that surprised people in the west was that electronic tubes was used in some parts of the radio equipment. After a while it was understood that the tubes where used so the plane should be able to withstand EMP. An EMP, (Electro Magnetic Pulse) is generated by the detonation of a large nuclear bomb in the atmosphere, the electric field so generated destroys most solid state electronics and EMP is thought to be used as a possible electronic warfare measure.
In the power supply of the main radio unit of the MIG 25 a previously unknown triode tube was used, the Soviet military designation was 6C33C and it was a voltage regulator triode. The data of this tube was much better than anything made before in the west and SanEi of Japan imported some 6C33C tubes for audio application in 1997, renaming them EC33C for the Japanese consumer. Mr. Dakesue in Japan was the first person to de
