Mine arrived today. Your usual super efficiency. And no postal nonsense, small envelope, very discreet. How nice. Thanks as usual. Now all I have to do is find time to build them.

Then it's true?! Shocked

they are moving from north to south pole Shocked

I'm trying to work out whether TL072's are worth getting in bulk or not? Any suggestions people? I'm sure this has been pointed out. I just have a head like a sieve! Shocked

cheapest I've found so far is 14p each (inc. postage), but then I haven't looked very far. Rapid are selling them at 33p each Shocked

reichelt.de sells the tl072 for 0,15€, but they don´t give discount on large quantities. postage has to be added.
banzaieffects.com sells them for 0,26€, but if you get 100 it´s 0,17€, if you get 250 it´s 0,14€. they also sell the obsolte tl072ip, a low noise version, for 0,36€...
so, if there is interest in a bulk order: banzai is located in berlin, and i´m quite often there to get parts, and i need some myself, maybe we can sort something out like a "small" group buy. that means i wouldn´t announce this officially, but if there is interest in this thread, i could get them at banzai and send them out. no shipping costs would be involved from banzai to me, so it would be just shipping costs and packing from me to you, which is approximately 3 euros within europe, plus the parts, of course.. all this of course just makes sense when we reach at least 100 pieces. i for myself will get 20-30 pieces.
by the way, banzai also sells some delay chips, ne570, xicon greenies, and other cool stuff. worth checking out...

if there is interest, please pm me.

best wishes,

tobias.

Hi,

This may be a silly question (probably Wink

)

Can you have five channels (as on Schematic)? rather than 4 (as on your front panel Fonik)

I'd like to use this with the Doepfer Vocoder modules you see and 5 would be better than 4,

Thanks

@ matthias

cool. thank you

@usine

sure you can. i guess fonik just uses 4 channels just because of space issues?

best wishes,

tobias.

THE RS mta connectors, can i get the part name and company that makes these? as as RS components seems to be euro only. or do they send to us?

(maybe mouser carries them? just dont want to wade through a million parts)

thanks

Very Nice design Jan!
Are you gonna do a some panel runs in dotcom format?
I am interested in the Wogglebug and Mixer panels!

uhh, and ...err... i know i wasn't consistent in the past, but i think i eventually set my mind and prefer the spelling fonitronik instead of fonitronic now Laughing
