Blues Jr Mods/Repairs

The Blues Jr is a Great candidate for mods with its small size and availability. We offer several Mods for the Blues Jr, from durability mods to tone mods. Email for Pricing!


1. Lower tube board Mod -The lower tube board is a major area of failure due to its thickness. Couple that with radiating heat from the tubes and transformers, and your have a breeding ground for failure. This mod replaces the thin circuit board with a 3mm thick hand-wired board with Belkin tube sockets and point to point construction. This will provide a lot of durability to an otherwise fragile circuit board.

2. Full Conversion to hand-wired point to point (Includes Lower Tube board Mod) – The Conversion Mod is a MUST for any Tone Junkie. Providing the ultimate in tone, reliability, and clarity. At a fraction of the cost, this mod will give you all the high, lows, breakup, and clarity of a full boutique hand-wired amp. The Conversion Mod offers a full hand-wired turret board construction using only the absolute best of components. i.e. SoZo Vintage spec or Jupiter signal capacitors, F&T Filter Capacitors, Ohmite Carbon comp resistors, and Alpha potentiometers.

3. Capacitor Replacement -Replaces all of the power filter and cathode bypass caps with high quality F&T Filter and Sprague Cathode capacitors. Many Blues Jr’s are known to have leaky caps due to subpar component selection from the factory. Along with this we can stiffen up the bass response by increasing the 1 filter cap capacitance. Just ask and we can make it happen!
