A Closer Look At The Lafayette LA-35B

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.

Magic Sam Live 1966

2 03 2009

The most incredible live performer the blues has ever seen, the magnificent Magic Sam!  “All Your Love” and “Magic Sam’s Boogie” played on a borrowed Les Paul copy from Earl Hooker through a Sound City half stack in Germany during the American Folk Blues tour of 1966.

19 01 2009

As the investigation into the Lafayette amp’s inability to function, startling new evidence has surfaced that could put an end to this riveting mystery.

Scotland Yard spokesman Neil Yarmouth was quoted as saying “It looks like the output tube has flamed out.” Investigators won’t confirm reports that the tube was simply 40 years old and failed due to old age but recent photographs suggest that is exactly what happened.

Lifting The Lafayette Lid: Tubes

Taking the chassis out of the Lafayette yields a nice view of the circuit.

The three tubes are plainly seen; two 12AX7 s, one shielded and one not along with the taller 6BQ5.

The could be the original tubes but are very, very old in any case.  They are all marked “Hitachi Japan”.

It’s a fairly clean chassis with a good bit of room between components except the circuit board is a bit crammed.

As mentioned before, a former owner played around with the Lafayette’s control nobs and I’m not too sure if either style on there now is what was on the amp originally.

The fat silver nobs look like they came off a hi-fi stereo tuner?
