What’s on *YOUR* workbench?

💯 I love the classic green that went along with some of the SH mono synths.

Friend of mine scored an RE-501 Chorus Echo and have wondered how many human sacrifices he had to offer to moloch to get it at the price he paid.

Did that Boss digital homage to the Space Echo have a chorus feature in it?

Good stuff. I imagine a real tape echo would be a beast to service, too, judging by the last time I dove into a tape deck and picturing that many times more complexity.

The echoplex isn’t much to look at. Space echo is definitely the cooler shelf decoration. Have you played with real tape delay units before? Anything I should look out for testing a unit in unknown condition?

I've used an echoplex before, but I haven't yet started to explore what to look for or what components are hard to source, if any.
 
I'm reworking something for like the 6th time. I built a PNP FF and a PNP Arrows on the same veroboard, and want them in a single enclosure. Once I got it in the enclosure, I had what sounded like a ground loop problem. I am beginning to hate this hobby.

EDIT: Well, it's all back out of the enclosure, and I have the many leads going to various spots on a breadboard so I can test all the pots. Turns out, the transistors are very sensitive to where wires are placed, and that was causing my noise issue. I have no idea how I am going to get this shit in an enclosure and make it work, but I already told my friend I am building it and it would be done tomorrow for our jam session, so I am committed to figuring it out. My hatred for this hobby grows, and strangely so does my motivation to conquer this hunk of silicon and shit.

Wife's soap-cutter had a catastrophic failure where the wing-nut bolt should be.

She ordered this contraption online; I wish she would've just told me what she wanted and I could've built her something more robust.

Note the guitar-tuner key on the right. Yes, this thing uses guitar strings to cut my wife's home-made soap-bricks into bars — so I save all my old unwound strings for when this thing breaks a string. It's worse than a locking-vibrato for breakage.


Anyway, I got lazy and it went on the back-burner; still lazy, I just glued the broken bit instead of drilling for a reinforcement dowel.


In the background is the drain tube for the humidifier repair, finished a few percent on Friday to make it 99.99% done. Just need to cut two tubes and fit them to a T and then have just one tube going to the floor drain.


Also on the workbench, my little breadboard for the New Year 30-bits or under build contest. "Life, you're in the way again."

Sweet layout! Do you happen to have the transistors' gains/leakage and collector voltages?

Ok I was playing around with this tonight again and I've landed on a completely different set as my favourite... For now.

I keep switching between an Oc44 in Q3 with pretty much the same hfe and zero leakage as the Oc78d but it sounds a little too gated at some settings.

It sounds really really good with my prs into my Marshall.

The battery is new and reading pretty high at 9.51v

Q1 OC81D
Hfe 153 leakage 175

Q2 OC81D
Hfe 83 leakage 124

Q3 OC78D
Hfe 55 leakage 78

Fuzz zero Full Fuzz
Q1
C - 9.45 9.35
B - 0.605 0.596
E - 0.542 0.531

Q2
C - 9.3 5.26
B - 0.047 0.132
E - 0 0

Q3
C - 9.28 9.1
B - 0.024 0.137
E - 0 0

Buys new fuses and fuse holder for ELKA 88. Puts said purchase up so I can find it when I feel like opening that can of worms again.
Opens can of worms.
Can't find fuses.

Update, found the fuses. Input them with all the other fuses, which are all auto fuses which are kept at a distance from audio-electronicals. It makes sense and I'll forget again(likely when I bow a couple after I finish the mod tomorrow/next Thursday.
Converting this from lamp wire to 3 wire because I'm a cheap-o and only bought 3 mains fuses and I want this guy to at least makes fun noises while it melts.
Scronged around to find a strain relief for the new beefier power cable after wasting 20 minutes trying to file the old one. they don't make plastic like they used to. On the plus side, I gave myself a 1/13 of a free manicure. So much winning.
The I needed to drill out the mains hole, you read that right. It's where the mains cable goes in the back panel, you read that right.
Well. Left me just say... They don't make hobo freight step bits from an equal or better steel than what this 1/16 thick sheet was forged from decades ago. Anyone need a plumb-bob?
 
This fucking build is CURSED. Everything works now, except the volume knob only goes halfway down (in terms of signal), like the ground isn't connected. Can't find any shorts. I'm out of IPA, so maybe tomorrow when I clean the breakout boards it will be fine.
