Rebuilding the Rockola Control Box 31115-A

I cleaned and measured the relays, connectors and switches, all of them seems to work!

The two old capacitors was replaced, one of them had loosen its capacitance so the replacement was really needed here!

I 3D printed a new nylon knob as the original knob was missing.

Recapping and rebuilding the Rockola amplifier 31451-A

As I bought a quite fresh amp I dont need to do anything on the outside except a little cleaning.

I decided to replace all caps and resistors just to be on the safe side.

I found new components at Elfa Distrelec https://www.elfa.se/, the shop is just 3-4 km away so I can easily go there by bus to grab what I need.

The two large 20 uF can electrolyt capacitors was replaced with six 22uF 450V.

I used a small blank circuit board for soldering all the caps and resistors.

I also replaced the PEC component with fresh new components on a circuit board 

All "small" components except the red diode and four large resistors was replaced.

After I replaced all components I measured them and I almost all was ok regarding the values so I assume the replacement was not needed at all!

I at least know the components will last the next 10-20 years.

Rebuilding Rockola Power Supply 31460-A

This weekend I did the Power Supply.

It was a piece of a cake this time as I have done almost the same on my Wurlitzer from -59.

The two capacitors and the rectifier was replaced with new parts, I also cleaned the relay, connectors and checked/replaced the four fuses.

Inside the PSU before rebuilding.

I removed the PSU cabeling and painted the PSU

Nice and clean with a new Silicon-Bridge-Rectifiers to the left.

I drilled out the all the rivets and replaced them with polished stainless steel screws,

 added waterslide decals as a replacement for the screenprinting.

Looks almost as new :-)
