Trace repair for this AKG N-Solidtube supply.

It appears the power transformers and varistors are a point of failure in these. Luckily in this one the transformer hadn't failed, and I just needed to repair some traces.

A colossal pain

This WEM PA100 came in for a general service as it wasn't working well, and needed an IEC power socket fitted.

I fitted the socket, fully recapped it, tended to some damaged traces from a previous repair, changed the output driver transistors for some matched ones and.... Nothing.

It would instantly oscillate as soon as the power amp saw any input.

After a few false assumptions and it being shelved for months I realised the problem: the speaker terminals were backwards!

This is now functioning perfectly and easily has a further 30 years in it or so. I think I prefer the ER/PA40 models but this is still a great amp.

Replacing the germanium transistor with a silicon one in this Hudson Broadcast so it can handle the heat and humidity better. Still sounds absolutely killer with the tiniest bit more bite to it.

Complete re-wired for this Hohner 'The Jack' custom V bass. Never had a headless instrument in before.

The wiringing harness had been ripped out by a previous owner, the new owner opted for a Artec Preamp to be installed. After cleaning up all the older points it was a pretty painless install. I do not like these style of jack sockets but I guess we're really limited by the routing as to what can be used here.

The blend control is passive so not the best way to do it, hence I'm designing my own onboard pre-amp unit.

Full pickup, pots, and switch swap for this Fernandez strat.

Nice and neat! Slowly but surely getting the hang of lead free solder.

Can't fix em all, some stuff just isn't worth it.

I believe these belong to Billy Kinsley of Liverpool Express and The Merseys fame.

The MXR Flanger is notorious for it's reticon BBD failing. These chips are extremely rare, extremely expensive, and are still not guaranteed to work. I did my due diligence checked the signal reached the Reticon ship. Checked it was recieving clock signal, but it wasn't outputting delayed signal sadly so wasn't an economically viable repair.

The Jen Motorphaser is a cool pedal. It originally had 3 footswitches: bypass depth and speed. The speed switch being unique in that it ramped the speed up or down between the two settings; much like a Lesley rotary speaker. Sadly it had been gutted in the past, and required a complete rebuild which was deemed too expensive by the customer.

Ah well, at least it was fun going over them.

A loose power socket needed it's joints reflowed on this Empress Reverb.

Never seen a surface mounted power jack before. Doesn't feel like the best idea.

A re-wired for this modified Colorsound Wah-Swell that came in alongside that 60s Fuzz Face.

The power socket had been added by the owner along with the colossal power filter cap. It had also been modded to just be a Wah with the swell function removed. I also believe the pot has been replaced. It looks like the ones Fender used way back when.

I rewired it to stock, added polarity protection, a smaller filter cap, and gave the pot a clean.

These are a bit weird as the wah function is backwards to accommodate for the volume swell function. Still doesn't stop it from being one of the best way sounds around. Seriously these old Colorsound wags are fantastic.

The big one!

I was foolish enough not to get pictures of the finished work. But an original late 60s silicon Dallas Arbiter Fuzz Face.

This had a range of issues. The wires had been crimped to the pots and weren't reliable which resulted in having to replace the volume pot. Luckily I had an ohmite pot of the right value in. I was able to swap the rear cover to maintain the original aesthetic.

It had been left open on a windowsill and the resistors had lost their colours. The owner requested I remove the resistors and rotate them 180° to show the colours that were left.
The input resistor has started to die so it was replaced with a NOS capacitor of the same make.

Wire dress was tidied up a little and it as on it's way.

As for sound?! It's a fuzz. I'm sorry. It sounds how you'd expect.

Here's a quick demo of the 4MS Noise Swash clone with nothing plugged into it.

Chirps and beeps galore!

This one was a long time coming. I bought this Russian Electronica 12-011 like 8 years ago with a missing LFO board for the tremolo and phaser sections. I rebuilt the LFO board and got the tremolo working, I rewired it all, changed the 5pin din sockets to 1/4" jack sockets, changed much of it to true bypass.

Sadly at the time the 6 stage phaser didn't work and with the cost of JFETs I decided to put the project on hold.

After doing some reading up on using a CD4069 as the control element instead of JFETs I decided it was the time to finish it off. The board built and much debugging later the phaser works! It's a bit limited but it works and thats the good thing.

The rest of it is weird. The compressor absolutely sucks. The pot tapers aren't ideal, the tremolo is pretty standard but the wah is fantastic! Very synth like, never heard anything like it. With the tremolo and wah on the tremolo LFO oscillates the the wah making for a cool hidden effect.

Built this clone of a 4MS Noise Swash for a customer. I don't think I've ever built a pedal this small with this many controls before.

It's a weird little circuit, a pretty conventional distortion circuit with a bent comparator in the middle of it, and then a global feedback path and voltage starve on top of that. It makes a lot of noise on its own before you plug anything into it.

I opted for on-off-(on) toggle switches so you can momentarily switch them if the owner desires.
