Looks like a few components have outlived their service lives by a few decades…

Tracing the circuit of the amp right now prior to changing out bad components and tubes.

Lafayette Bass Amp Confirmed As LA-35B

15 03 2012

Needing a reliable bass amp, I removed the chassis from the old Lafayette bass amp and was surprised to find the model number stamped on the circuit board.

I’ve seen other photos online of similar circuit boards in amps made by Univox for Lafayette.

Huge transformer really gives the chassis a lot of weight! Next up, I’ll be replacing all 10 capacitors in the circuit and re-tubing it as well in hopes that it results in a usable bass amp for recording.

Mystery Lafayette Tube Amp: LA-35?

31 10 2011

It’s a rare occurrence when I run into an old Lafayette tube amp and I just had to pick this one up last year when I saw it in a music store. The picture below shows it in the store.

At some point in it’s life, someone had bolted a homemade wheeled stand to it’s bottom. Looks pretty bad but comes in handy.

With the 15 inch Jensen and a horn handling speaker duties, I think it’s a bass amp.

There is no model number anywhere on the amp. Research has led me to believe it may be a Lafayette LA-35?

As you can see, a lot of the internal components need replacement.

Solar, Sangamo, Beaver and Mighty Mite caps all on display.

This amp was made 79 years ago and the tube complement is a bit different than what is found in amps made in the 1950’s to present day.

The preamp tubes consist of a pair of 6N7 valves while the phase splitter is a 6F6GT and the output is provided by a 6F6-G tube. Rectification duties are handled by an 80 tube.

Ever seen another amp with these?
