As there are still quite a few people starting to build the 9090 , I would like to help out with organizing a possible groupbuy.
If there are enough people (minimum 10) I could make a few big orders with the different suppliers and send you a complete package with all the components or just the rare parts.
I am not doing this to make money at all, I just want to facilitate the new builders. So I will not advance money and will only send what is paid for.
I have shared a spreadsheet, in that file you will also find a few columns concerning my sequencer part, don’t worry about those columns as I have not yet finished the sequencer. That will be done at the end of December.

Definitely interested. Would it be full kit including panels? I have a lot to solder at the moment, but I would be interested to get a full kit for future use… for the next soldering season Next summer, here we come
Yes the 9090 boards will be included for everybody that wants them. I have contacted Trevor and he will send the boards to me, so I can send them onwards.

I have sourced all of the components (except the pot meters and transfo), I have an estimation of the price, it will be around 320 euro’s. depending on how many people enter the group order.
This includes
the Trevor Page boards PIC and PROM’s and all the components needed to build the 9090 (except the pot meters and transfo).

and much, much more (resistors, caps, connectors, heatsinks, …)
Put myself on the list for rare parts+components, but I have a special request: I already have the M5218AP opamps, would it be possible to leave them out for me? I already have the 9090 PCB’s, too. I’m not interested in the sequencer.
Other questions:
-you won’t be including 2SA798? (I would like these)
-you won’t be including 1SS133? (I don’t mind these)
I’d totally be on this like a fat person eating a burger (looks at self) if it was possible to get just the seq PCB. Thinking about putting that in a table top “remote” for the existing rack.
Added myself to the list for the SEQ-related bits just in case. Edit: I haz a belly… which is melting off
Julian F did my panel just beautifully (need to put it on Flickr) so I’m going at it Prophet 3000 stylee since the rest is already done. I fear a dramatic failure, but you have to take some risks in life.
Next summer, here we come
