Buchla Easel Mods (Dunnington Audio or Others?)

Post by bishun » Tue Jun 26, 2018 12:14 pm

SEE: dunningtonaudio.co.uk

I've been trying to reach out to the store owner for quite some time, as I would like add the self cycling envelope and switchable range for the modulation oscillator, as well as the infinite sustain module.

I haven't heard anything back from e-mail, facebook, or instagram :(

Is there anything/anyway else readily available to achieve the same goal? I'm the process of finishing a 208 (Roman v2) build and would very much like to get it done in one shot.

Thanks in advance for any help.

Self cycling envelope and switchable range for the modulation oscillator are standard on the ToolBox that's on the way to you ;)

Ahhh, that's right! I think I would prefer to use the ToolBox - so that just leaves the infinite sustain module I suppose.

For the out of stock EG sustain module I can't help. Tarandfeathers (who runs Dunnington audio) said he won't do another run but maybe if enough builders insist...

I still have some EG looper PCBs that I did before the ToolBox, if someone wants one, I can send it free of charge, just pm me.

The MO range switch needs no PCB, it's just a switch connected to +/-15V via a 120k resistor and a trimpot for scaling.

I'm considering another run of the infinite sustain module. I have had a number of expressions of interest, but still not enough to break even on a production run. However, I have managed to get an acceptable quote for 25 pieces. The price will be slightly higher than the first run, but not by much. I am waiting for a quote on assembly of the looper/range switch boards as I simply don't have time to assemble these by hand currently but since these are single sided and low parts count I think they should be reasonable to have made.

If I go ahead I will probably do 25 of each and I am pretty sure that these will be the last runs of these modules.

No worries, i think there's enough hunger for another run :) I know I would be ordering multiples myself.

Okey, I have just placed an order to restock both of the mod boards. These should take around a month to come in. I will not be accepting orders until I have everything tested, so expect them to be available again mid-late August.

Thanks for the interest everyone.

I'm about halfway through testing the new boards, packing materials are on order and should be arriving in the next day or so, so I expect to be adding stock to the store this weekend.

Thanks folks. Everything is tested, I'm waiting on one order of packing material but I should be able to start shipping out Friday at the latest.

Anyone who could send some shots of Dunnington Audios Music Easel Infinite Sustain Module installed on their 208r rev2? Kind of worried to install it, because I've only soldered few things so far.

There's a pic and mounting details on https://www.dunningtonaudio.co.uk/produ ... in-module/
Nothing complicated, but a good desoldering tool is recommended to avoid damaging the PCB traces.

If your ICs are mounted to this type of sockets (not the ones with round eyelets) you can just remove the ICs and insert the module into the sockets, no (de)soldering is needed.

Thanks Papz. Yes, if you have wiper contact IC sockets, the boards will fit, but it will deform the contacts in the socket so they will no longer hold an IC. It's also likely that this will put stress on the solder joints of the pins on the sustain board so for long term reliability the preferred method is as stated to remove the original ICs and sockets, fit the supplied sockets onto the sustain board then solder the whole thing into the envelope card, or as Dave Brown mentions, solder the sustain board directly into the envelope PCB.
