HF-2501
PROJECT: HF-2501
DESCRIPTION: 6P45S PA in two FM302 cases
STATUS: e l z
PROJECT START DATE: 1994...1996
LOCALISATION: -
DOCUMENTATION:
DIMENSIONS:
It was my first tube PA. It has been made on Soviet tube 6P45S. In 1990s this tube was very popular in Poland because it was used in Soviet TV sets like RUBIN and ELEKTRON (it had very big and colorfull CRT and needed strong driving). This tube can work up to 120W to 30 MHz! In capitalistic electronics never such powerfull elements were used in consumer electronics.
Two FM-302 cases were used to construct this PA, tube 6P45S was in upper case and power supply was in lower case! At that time for some technical reasons I couldnt made it in one case, but after years I made it, see HF-2508. HF-2501 was soon obsolete and was dismantled, maybe in 1996 year.
HF-2501 was used for amplifying my 1 watts only CW TX HF-2301. One of first confirmed by QSL radiocontacts was QSO with station ST2AA.
