Alpha SR1712F series. I use 'em myself -- they work nicely with 9mm pots (mostly...)

They can be a bugger to get, though.

Thanks that should help the search. I'll bring a sledgehammer ;)

Open Discussion / Looking for EHX Qtron+ SPDT switch
« on: May 05, 2020, 11:01:14 AM »
I'm looking for a bulky, square SPDT switch used in the EHX Qtron+. It's the boost switch on the unit that's gone faulty. I reached out to EHX but haven't hear back.

Picture attached, it's the switch on the far right.

One cap is rated at 50V and measures 26V across the terminals, the other one is rated at 25V and measures 15V across the terminals. So that should be all within safe limits although there's probably some unnecessary heat dissipation. Would you advise to swap it for the 15V?

I got the 15V and 18V transformers in the mail past wednesday. The eyelets on both are much wider than the datasheet had me suspect, so both would've been a good fit. I installed the 18V transformer and the Memory Man is working fine. Thanks to Scruffie! Only thing left to do is get two nuts and bolts to mount the transformer and it's good to go.

Ordered, I'll be back here in about three weeks I suppose ;)
Thanks for all the help Scruffie!

Nice find. Screw holes should be 45mm apart, sadly the ones in your link are quoted to be 42 apart. I can probably find a work around for that though. This 2W 12/15/18V one from the same seller might be a better option?

Considering choosing the easy way out and just installing a modern pedal jack for a wall wart.

Also have little experience reading tranformer specs. I found this one, but can't find the full specs. It seems this is 25V input, so not suitable. Right?

If I go with the wall wart option should I (re)wire anything to the center tap on the circuit board?

Open Discussion / Re: Lets talk about strat pickups
« on: March 28, 2020, 05:39:02 PM »
I've got a strat with pickups wound by Timbo in it. I set up one of the tone controls to blend in the middle pickup (in series) with the bridge one (on position one). You could also put it on a switch but I like the original esthetic of a strat. Close the tone control and you've got that strat single coil bridge sound, open it up and you get a faux humbucker. Way to muddy for clean tones but excellent with some drive and gain.
That said, I'm probably going to swap the bridge PU for a single coil size Air Norton.

Set delay to max, unplug the input and adjust the 1k 'balance' trim while audio probing its middle pin.
Remind me, how much am I paying you again? A 1 degree turn of that trimmer and the whine is gone.

Now to find a suitable transformer. The F-115X is not the right one since being in Europe we use 230V, not 110V. Any suggestions for a suitable replacement with the same form factor?

Necro bump, but still. I had put this unit on the shelf for a bit and haven't looked at it in a while. Took it out today and miraculously it's working. Guess my last iteration of repairs did the job but I hadn't noticed it. Doh. There's now a bypass signal and a delay signal, so the SAD chips are ok. The only thing is there's still a low volume high pitched whine riding on the audio. I'm thinking that might be due to the walwart so I'm going to look for a replacement transformer and also replace all remaining electrolytics. Any other suggestions to combat the whine?

Great looking builds outside and inside!

p.s. I'll hook you up with some more stuff to build, hopefully soon! As promised!

That sounds like a real roller coaster what he went through. Get well soon and back to strengths Rej!

Forgot to steal that waza pedal for a few days. Will try again soon.

I just want to mention that I went to see X-Men: Dark Phoenix today and I thought it was EXCELLENT for the most part, as far as I'm concerned. It gets shit reviews but I only got a little bit distracted in the middle of the train scene at the end. I see some possible improvements (like the aliens being actually quite redundant) but it felt REAL and convincing to me. Something most MCU movies, especially the Avengers ones, fail me on. It think, together with Logan and Days of Future Past it makes my top 3 of X-men movies. Sadly, most X movies aren't that much to write home about. This one was, I believe, well executed at least.

On a related note, I'm always a little amazed at the insanely high ratings, by critics and audience, the Avengers movies receive. Other example: Pacific Rim. I'm going to rewatch that to see what I think about it now...I just remember it did NOT live up to the rave reviews as far as I'm concerned.

Related note #2, tying in to the LOTR 'plot hole' discussion: the way Midwayfair explained that one actually makes sense in that universe. All powerful beings in other films, like a Captain Marvel in Avengers, are much less satisfying. My girlfriend said that Jean in Dark Phoenix is a little like Captain Marvel in that regard, which sold the story short for her...and I can see that in hind sight, but it didn't bug me in the theater (Captain Marvel DID though).

I'll borrow a Waza from the guitar store I do repair jobs for and check the insides after the weekend, see what I can spot.
