Lafayette (Univox) Vintage Guitar Amplifier U-235-PB

Welcome. Thanks for stopping in. Please read entirely and carefully. Up for sale is a Univox U-235-PB Amplifier restoration. This one is Lafayette's version. It is electronically identical in every way to the Univox model. One unique feature of this unit is the model number U-235PB is debossed on the front faceplate. This is the only unit of this model like this I have come across and goes a long way to clearing up ongoing confusion with this amp's true model number. This unit is SN28286 manufactured in Japan in the late 1960s, most likely 1967-68. This amp is fully restored and in excellent condition.

Originally sold as a Bass Amp, this amp is also good for guitar. It has Bass, High, and Low inputs, Deep and Sharp switches, and incorporates the James tone stack which uses Bass and Treble controls. This amp sounds great, has low noise, has been burned in, and extensively tested and documented. This amp has been completely restored and includes a number of safety and protection upgrades including IEC power cord connection with grounding, AC line safety capacitor, varistor surge protection, HT fusing, an HT discharge resistor, and OT output protection resistors. The power transformer is original but has a new Classic Tone Output Transformer. All power supply and coupling capacitors, resistors beyond 10% of their original ratings, and all potentiometers have been replaced. An adjustable fixed bias circuit has also been added. All new Tung Sol valves (tubes) are installed including 12AU7s in the Preamp, Phase Inverter and Driver positions, and 6L6GC-STR Output valves. This amp has its original black Tolex which has been cleaned and repaired, a mix of new and original polished hardware, and new rubber feet. A new polished aluminum heat shield shows off the valves very nicely. There are minor scratches, imperfections, and metal oxidation typical of an amp over 50 years old. This amp achieves clean output up to 32 Watts RMS. This amp is provided with schematics including one showing all mods and parts replaced. A cover with a unique custom Lafayette Emblem sewn on the front is included and will keep this amp looking its best. A pocket in the cover is provided and holds the power cord.

This model is commonly mistaken for a Model U-1235/1236 (among others). The U-235-PB actually preceded the U-1235/1236. Part of this confusion may have come from a schematic not being available for the U-235-PB model (which is now available). These models have nearly identical post power supply design, however the power supply in the U-235-PB is lower voltage than the U-1235/1236, is lower wattage, and uses a 12AU7 Phase Inverter instead of a 12AX7. A picture of these two models together is posted to show the differences (for reference only, not the units for sale). The U-235-PB model is on top. As you can see, inputs and controls are identical, just different size and color faceplate.
