Univox Vintage Guitar Amplifier (Amp) U-1221

Description: Welcome. Thanks for stopping in. Up for sale is one of my Univox U-1221 Amplifier restorations. This unit is SN-56737 manufactured in Japan in the late 1960s early 1970s, most likely 1969-1970. This amp is fully restored and in excellent condition. Intended for guitar, this amp's tone circuitry and effects remain true to the original designer's intentions. This amp has lots of vintage sound and plenty of punch.This amp is equipped with two (2) channels, each with Normal and Bright inputs, Volume, and Tone controls. Channel 1 incorporates, additionally, a Reverb circuit with Depth control, and a Tremolo circuit with Speed and Intensity controls. Both effects are full and deep. The Tremolo does not thump, and the Reverb is not harsh. The Reverb circuit incorporates a new Revisit Reverb Tank better matched to the circuit impedance. This amp achieves clean output up to 42 Watts RMS. This amp is equipped with an all-vintage pre-power tube line-up, and includes a matched pair of vintage Toshiba 6L6GCs. This amp has low noise (a choke, similar to the units in the higher power Univox units, has been added to keep noise in check), has been burned in, extensively tested, and documented. This amp is provided with schematics including an As-Built and one documenting all mods and parts replaced. An impedance selector switch allows for choosing between 8 and 16 ohm outputs. A new customized footswitch with LED indicators can remotely operate the Reverb and Tremolo circuits and is included. A cover by with a unique custom Univox 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.The U-1221 is the big brother to the earlier U-320 (which uses 7591 output tubes instead of 6L6GCs). These models have similar post power supply design, however the U-1221 is higher wattage. The tube line-ups are similar with the exception of the phase inverter and output tubes. A picture of these two models together is posted to show the differences (for reference only, not the units for sale). The U-1221 model is on the bottom. As you can see, inputs and controls are identical, just different size, knobs, and color faceplates.This amp 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 transformers are original. All power supply, electrolytics, and coupling capacitors, resistors beyond 10% of their original ratings, and all potentiometers have been replaced. An adjustable fixed bias circuit has been added. An internal low speed, low noise cooling fan assists the natural convection cooling to reduce internal temperatures (20F by my testing). This amp has new knobs, a new case, new black Tolex , a mix of original and new hardware, and new rubber feet. There are minor scratches, imperfections, and metal oxidation typical of an amp over 50 years old.The return period for this unit is fourteen (14) days after confirmed delivery from UPS is received.
