Description
YAMAHA B-2 V-FET power amplifier Meter lamps, blue LED Maintained Works well F/SDescriptionUsed ; It has been confirmed to work. There are some small scratches due to age, but it is generally in very good condition.*Please refer to the images. This is the B-2, a V-FET equipped power amplifier released by YAMAHA in 1976.This is a famous Yamaha model born in the era when the domestic audio industry was at its hottest, and many new elements and circuits were developed and competed with each other.The V-FET is a voltage amplifying element that is very attractive because it has characteristics similar to those of a vacuum tube triode.Also, the meta-can type installed in the V-FET is a valuable element that does not exist today.The meta-can type installed is a valuable element that does not exist today.B-2 is equipped with 2SK76 (Nch) and 2SJ26 (Pch) power FETs, newly developed at the time, which are smaller and complementary to the V-FET, 2SK-77, developed for B-1.This unit has undergone maintenance and refreshment, including disassembly and cleaning of all selector switches, push switches, and relay contact point relations, and replacement and adjustment of many parts such as volume, electrolytic capacitors, and semi-fixed resistors.In addition, the meter lamps have been converted to multiple high-brightness LEDs and are blue in color.All parts have been replaced with highly reliable ones.The output terminal, which is a drawback of this model (fragile), has been replaced with a large gold-plated type, which is also compatible with banana plugs. Replacement of electrolytic capacitors (amplification and power supply boards) except for large electrolytic capacitors for power supply ? Nichicon Audio, FineGold, etc. - All new semi-fixed resistors for idling current, zero balance adjustment, and voltage adjustmentReplacement ?Replacement of all meter board semi-fixed resistors ?Replacement of all front panel volume ?Changing meter lamps to LED ?Replacement of some small signal transistors ?Removal of carbonized small signal transistors with blackened legs ?Speaker output relay - Disassembly and cleaning ?All front panel push switches - Disassembly and cleaningFront panel push switchesRear panel input switching slide switch disassembled and cleaned.
