I made a start yesterday, mostly metalworking. Not my strong point. I roughed out on paper what I wanted and where it was to go but the first job was to make sure it would all fit. The space inside was large enough, it was the area on the front and rear fascias that as most critical especially as I wanted a power distribution section to keep the number of power leads trailing to a socket to a minimum.

As it turned out the biggest problem was the height inside the case. The pot solder tags project too high and would touch the lid if I didn't turn them and the jack sockets that Nik supplied have great long solder nibs which were also a problem. I swapped them for a different sort, but in retrospect I should have drilled the holes slightly off the centre line.

The 9v transformer I cannibalised from a linear regulated supply house in a plastic case, which was inordinately difficult to get apart, they glue them together it seems, had to resort to hack saw to get at the innerds. I also had to separate the regulator from the tranny otherwise the  contacts would have been above the level of the lid. As it was I had to cut a hole in the lid for the transformer but there's no risk of contacts touching now.

Front face plate from left to right. Send, Bright switch, return, bright switch, recovery, Bypass LED, 9v fuse, 9v power LED, 9v power switch, Mains fuse, mains power.

Power socket wiring now completed. 9volt wiring partly completed, sufficient to power it up and check the tranny, regulator, LED, switch etc. The green LED is on just not very bright, deliberately, I don't want it looking like the bridge of the Enterprise.

Face plate and outside of case was sprayed matt black

Star ground fixed but not all connections made.

Jack sockets were a pain. there was very little room to manoeuvre under the lip so I tack soldered the solid earth connector then removed the sockets to complete all the other wiring. I also took the relay board out and colour coded the connections for later reference.

Bypass switch was a very tight fit, but I wanted a very robust one. This is the one you'll hit if something goes wrong mid song!!

Rear fascia is, from left to right in the photo, Input, send, return, output (reversed from Niks layout), bypass switch, footswitch jack, two 9v out sockets, 3 mains power out sockets, mains in socket.

Hi

Have you built your Kleinulator to the latest soecs?
There has bee a small addition to prevent tthe unit from blowing up.
I don't know the technical details but it includes a Zener (whatever that may be)

Turns out my board was built before the new mods. Nik is sending me the parts to upgrade it. Layout was correct.


This might cause a bit of a delay in finishing the project.

10ohm resistor.

My 9v supply is rated 500mW which I would hope will be sufficient. All the filtering is part of the Klein kit though somehow voltages higher than 9v are being generated. My electronics knowledge is insufficient to understand how!

Those that know might chip in here !!!!

Somehow the circuitry is generating 20+ volts from a 9v supply so I guess that chip might have something to do with that.

Depending on the diodes used, you can get a voltage from your power supply at 30-40V.
This link posted at ampgarage explains it well. http://www.geofex.com/circuits/+9_to_33.htm

9v supply to relay board and to 9v outlet sockets.
