Old Bronson Amp gets flabby Field-Coil speaker replaced

This made-in-Detroit Bronson amplifier came in needing all new capacitors, new power cord and a new speaker. The original field-coil speaker was blown in a recording session and was replaced with a new alnico Weber. The original output transformer was removed from the speaker and reused and a choke was added. Mallory 150 film capacitors were used inside to retain a vintage tone. This is a killer amp!

Fender Princeton Chorus – Bad Repair Fix

This Fender Princeton Chorus came in not working and had been taken to someone else for repair previously. Bad solder joints on key components were to blame, and once everything was cleaned up and done properly the amp functioned again.

Bad solder joints here.

McIntosh MC-240 new capacitors

This beautiful McIntosh MC-240 stereo tube amp came in with all original capacitors. We replaced all of the electrolytic cans with CP Manufacturing cans which are made on the original Mallory equipment and are drop-in replacements. Most recaps on these McIntosh amps use lower quality capacitors here and require holes to be drilled in the chassis to mount them, but keeping the amp original is important. The other electrolyrics were replaced with Sprague Atoms and film capacitors were replaced with 716P Orange Drops. The original “bumblebee” film capacitors were left in-place at the request of the customer.

Modifying a Fender Excelsior

A musician brought in his Fender Excelsior, unhappy with the two-position tone control (who wouldn’t be unhappy about that?). We changes some components on the circuit board and replaced the switch with a potentiometer, and now the tone control works just like a vintage Fender Tweed Deluxe and goes from bright to dark and every setting in between.
