Retro-King Intros 45 Watt Combo Amplifiers

retro king ampRetro-King, a maker of custom retro-styled amps, has introduced the 45 Watt Combo is a replica of the famed 1960’s Bluesbreaker 2×12 combo. Unlike the reissue, this amp is hand-wired point-to-point on a vintage style turret board and is built to the exact specs of the original (a 100 pico cap across the normal volume is added for additional clarity).

The output tranny built for Retro-King by Heyboer with the 6.6k primary plate load 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 77k (mounted on back of amp). This will give you more or less power amp gain. Eric Clapton beano tone to AC/DC, its all here.
