Re: Synthi Hi-Fli CLONE/boards

Wow, I had forgotten all about this until I got the notice yesterday of a new post. Just ordered a set (plus a couple of others) from deadendfx.

Re: Buchla 100 clones: 158, 180, 140, 156, 106, etc. DEMOS

After getting a few requests for more details and plans, I updated the 100 Cabinet construction page:
http://www.guitarfool.com/Buchla/100cabinet.html

I only had 2 spaces left (how did that happen?), so I built a 4th cabinet.

Yay! :banana: Mouser finally got the Grayhill rotary switch for the 146 (PN: 706-51SP22-01-1-15S) in stock again! But they only have 22 of them - get them before they're all gone again.

My 2 281r's don't trigger it (except sporadically), but my 280r and 259r (mod oscillator CV out) do.

Okay, here's a dry run of what I'm going to attempt tomorrow at the Electronicafest https://soundcloud.com/user-558302218/kling-und-klang It's all La67 stuff until 06:45, when the 200r (black knob stuff only) starts in.

For anyone in the Baltimore-Washington are (close to BWI airport), I'll be performing on my La67 system on Saturday November 3 2019 (see info HERE).

146 and 112b are now available at Modular Addict (as well as restock of the ones they ran out of). :nana:

So I need a BOM for the 146 :wink:

Not that I can see. I just checked 2 BC550s and their Hfes were around 350! Oh yeah, watch out for the pinout :bang:

Thanks. Now I just need another 160 PCB (just ordered from you) so I don't have to use a cable for an input source. I noticed without the source cable plugged into anything, it still works somewhat. I guess there is enough extraneous noise in the input circuitry (plus the cable as an antenna) to get...

New modules are up at ModularAddict, in case people hadn't noticed. There's a problem with the 165 panels... am in touch with MA & Mr. La67... will update when it is resolved. Yeah, I noticed. I just used a step drill to enlarge the holes to the correct size. Oh, and PCB scans for the 102 & 165 are...

Since I'm now waiting on parts, I took the time to put up some Buchla 100 build info on my website HERE . Not much on build notes yet, but at least I uploaded board scans of most of them (all the ones I have). Feel free to PM me if you have anything to add, corrections, omissions, whatever. :wink:

For the 114, the 10k linear pots are 9mm, right? (like these)

The link to Tayda on the BOM is for the larger ones :hmm:

Okay, I just finished the 191 - except for the rotary switch which is still a month away :cry: I found a couple of discrepancies in the BOM. The 4 DPDT switches should be SPDT - I used the C&K (Mouser 611-7101-002). There should also be 4 Large Davies and 3 small Davies knobs. (edit: 3 small Davies ...

Mouser is out of the rotary switch needed for the 191 (it wasn't me that bought them out), and the only other place I could find was Digikey - with a minimum order quanity of 25 :eek:

Mouser is guessing at getting another small batch of them near end of June. :sadbanana:

As is, it's a great idea for use as a filler / blank panel. Same goes for the model 199 Silence Generator
