New Amp: Orpheum 700

3 02 2009

That old Orpheum amp that I’ve previously discussed in the “Sightings” section of the site was still for sale on a recent visit to my favorite music store.

So I bagged it and will be featuring the old boy during the month of February as the Lafayette continues to undergo repair.

Output Tube As Culprit In Lafayette Mystery?

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.

Some good closeups of the pots and input jacks.

Also a good perspective on the power transformer and a big electrolytic capacitor.

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.





Lafayette Front Panel: Nobs And Jacks

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?

Upon Further Investigation…..

15 11 2008

As will be seen, this Lafayette amp is a fixer-upper. It wasn’t well cared after and someone took liberties with the control nobs, but the little thing rocked during the brief time that it worked.

At the moment it consumes fuses like there’s no tomorrow and presents a good learning experience to find out why. I bought this for just $75 about two years ago where I found the Silvertone 1470, purchasing both in the same transaction.

When running single coil pickup guitars through the amp, it produced a very ratty 1960’s garage rock tone, all treble and spite with hardly any bass response. Forget lush, swirling, harmonically rich chordal moments, this is real bare wires stuff, like a budget version of the guitar lead on “Sympathy For The Devil” by the Rolling Stones.

I wish Lafayette had come up with a model name for this amp, there’s no joy in referring to it by its given name of 99-9141WX. Fender had the Twin Reverb, the Bassman, even the long forgotten Bronco, Gibson gave it’s amps names like Ranger, Minuteman or Medallist, while Vox combined letters and numbers in an interesting way to produce the AC-10, AC-30, AC-50…etc, but to Lafayette, amps were just catalog order numbers.
