A Video Look At The Kent BA-170, A 1960s Bass Guitar Amp

in #guitar-amp2 years ago

Hello, hivers!

About a month ago, I posted a short video about a vintage guitar amplifier that I had repaired, the Kent DR-57 amplifier head. In the beginning of that video, I showed both that amplifier and the one that this video is about. I edited this video to use the same introduction as the other video, because this amplifier was included in that introduction. That post can be found here.

I also previously posted about the repairs that I did to this amp. That post can be found here.

The Kent BA-170 bass guitar amplifier head was built for a couple of years in the mid 1960s. This amp uses a pair of EL-84 power tubes to generate about 16-18 watts of output power. This amp head was designed with a bit more conventional preamp circuit, for the time, than the DR-57 had. The amp had a volume control, a treble and a bass control, and speed and intensity controls for the tremolo circuit.

Here is my video about this amp.

I hope you'll find this video informative and interesting.

This amp uses a pair of EL-84 power tubes to generate about 16-18 watts of output power.

Is that tube made by Tungsram? If yes, then it is very good to see a Hungarian product. Of course, Tungsram has factories worldwide, so the tube is maybe not created literally in my country (Hungary), but somewhere else in the world.

The power tubes in the BA-170 are an old vintage pair of U.S. made 6BQ5s, the U.S. equivalent of the EL-84.
A lot of the old amps that I work on have tubes in them that are about as old as the amp is.
There's almost no tubes made in the U.S. now.
