Dyno My Piano - Tri Stereo Chorus
Hi all,
during 2012 I looked at these videos:
http://www.youtube.com/watch?v=n95DPQqKFd8
http://www.youtube.com/watch?v=L3I6euvvLFc
and I tried to find something related to this effect.
No schematics around, just some unlucky heuristic.
So I just tried to collect some information about it starting from:
http://i235.photobucket.com/albums/ee11 ... chorus.jpg
http://i692.photobucket.com/albums/vv28 ... rdCaps.jpg
From the two images, with the latter as a reference I supposed:
- on top right of the pcb: dual supply with 7815 and 7915 voltage regulators plus a 7805 voltage regulator;
- on center-right: three standard MN3101 MN3007 chorus;
- on center-left: three compander NE570;
- on top left: some JRC4558s;
- on right: some JRC4558s;
- down on left: preset/manual switches;
- down on the center: something like square-sine-triangle generators with each own "master volume" to determine the waveform so how the delay of the chorus works;
- down on the left: a single OPamp based oscillator.
Even more, few days ago Fulltone declared he has replied the tri stereo chorus, including some pictures:

Someone has some more ideas to share?

Re: Dyno My Piano - Tri Stereo Chorus
Dytronics Tri-Chorus always reminds of Mike Landau's Tales from Bulge and his 80's Yellowjackets clean tone.

Re: Dyno My Piano - Tri Stereo Chorus
I received the pre-release notice a few weeks ago, so hopefully it shows up soon. Always regretted that I traded away the TC1210 and always wanted one of these units.BIG Dave wrote:Fulltone TERC (That 80's Rack Chorus) is now shipping!

Re: Dyno My Piano - Tri Stereo Chorus
Did you receive an invoice from Fulltone and paid it? I did. I was given my serial number and was told and it would ship out by Friday of this week.ToneMerc wrote:I received the pre-release notice a few weeks ago, so hopefully it shows up soon.

It would be nice to see something, if possible.

Paid the deposit, haven't seen the final invoice. Did you request a certain S/N?

Re: Dyno My Piano - Tri Stereo Chorus
I was billed a $250 deposit on March 20 and at that time requested a certain S/N. I was told that S/N had not been previously requested and I could have it. On April 1 I was billed the balance ($1,029.05), and asked which voltage version I required (100, 120, or 240 VAC). After paying the balance, I received a confirmation email that my requested S/N was reserved for me.

Which serial numbers would you say sound best?BIG Dave wrote:I received a confirmation email that my requested S/N was reserved for me.
Re: Dyno My Piano - Tri Stereo Chorus
Everybody knows that even serial numbers sound better that odd ones.
