Making a new battery door for green russian Big Muff
« on: March 17, 2019, 09:43:01 AM »
I purchased a "bubble front" green Russian BMP, but is was missing the battery door.
The original door uses spring locks on both sides, and are just pushed in. I had this sudden idea to make just one spring out of a Keystone battery clip, which seemes to have just the right flexibility and shape.

1. I used a 2mm thick aluminum sheet, 6.4mm x 3.1 mm for the door


2. I cut and bent a Keystone battery clip so it could work like a spring lock




3. This is how it looks after i have assembled all the parts together (i used rivets and a 3mm screw). The piece of metal on the other side is there to be slipped underneath the enclosure, no need for another spring.



4. And this is how it looks on the Muff itself.

It's not bad. Comparing to Ram's this one feels less aggressive, less bassy, and it is very low on hiss (it uses kinda big emitter resitors).
