Retro-King Intros Plexi 45 Hand-Wired Amp

retro-king ampRetro-King has introduced the Plexi 45, a replica of the mid 60’s JTM 45 amplifier. This amp is hand-wired point-to-point on a vintage style turret board and is built to the exact specs of the original (Retro-King adds a 100 pico cap across the normal volume for added clarity).

The output tranny is built for Retro-King by heyboer with the 6.6k primary plate load which is optimal for the kt-66 power tubes. As in the originals, the filtering in the first cap is a double 32mf cap and the second is a double 16mf cap. This amp uses the early “plexi” tone control values along with the standard preamp values. You can also order this amp with the optional negative feedback control adjustable from the stock 27k to 47k. This will give an increase in gain. The Plexi 45 is also available in a 2×12 combo.
