If it’s a head count I would be up for 1 maybe 2 if I had the money at the time

JH have you dropped the Deltalab delay board?

I don't spend much thought about it at the moment at least.

Any delay PCB that is CV controlled for Rate and Mod would get an order for two PCB's from me. Even better would be to allow the external DC adapter so it could be built into a larger pedal enclosure for guitars with expression pedals.

Thomas

Time Machine's go immediately when they come up for sale. So fast it is hard to ever find one. I need a Jurgen delay!!!

Big question is why has John discontinued his Time Machine, if there is so much demand for a delay, and enough supply of BBD chips?

JH.


What i know is that the TM has several hard to find parts, but i could not tell you how hard.
The other thing is that there where fake 3005ers out there.
Dieter doepfer warned me about this, nomore shure if he directly told that he got fakes. ( but i think he did get )
while mailing with Dieter ( it was about modifieng his 4096stager to have 2x 4096stages ) there showed up 100x 3005ers on eBAy, i asked him if he knows that vendor.
Well the next Day they where all gone. Laughing but that must bot been him .
since then the 3005ers showed up only every now and then and only in _very_ small quantitys.( ok, i don't checked so often )
there has changed definitly something !
when making now a surch at ratbay you get several Vendors that seem to have some more than just a handful


---> Jürgen, would your Board also take just a single BBD, 256 or 512stages,
so that one can either build a Delay or a more Karplus strong/FX oriented BBD ?
If so, it would double up my number

Well at the monet it's just a vague idea.
But I think it won't be hard to allow BBDs of different length to be used.

Count me in! Cool

For good availability and cost, perhaps consider the cooaudio BBDs...

Yep, just an Idea, but a nice one Wink
If the Board is good for universal use, i think i would take 8 ( and sell my doepfer BBDs )

These are from the same series of BBDs that also are in Behringer's Dimension C clone, aren't they?
I thought that Behringer stompbox did sound snice, especially for the price, if it wasn't for that horrible overload behaviour. Maybe it's due to these low-voltage BBDs. I think the old, 15V BBDs have a rather pleasant overload characteristic, especially in combination with low pass filtering. And if you add a vactrol limiter with fast response time, it's analogue bliss. I'm not sure the same can be achieved with these low voltage BBDs. I don't say it's impossible - I just say I wouldn't know how to do it. For the MN3005, I have experience from modifying an Amdek Delay Machine. (That haunting noise on "October 96" from my first CD is just a few notes from the CS-50 caught in that Vactrol'ed MN3005 delay with infinite repeat.)

synth_ollie was selling some in the parts buy/sell section of this forum
he got them from chipforbrains/technologytransplant

ive researched the hongkongsupperseller 3005s and sounds like there have been a few instances of him selling repackaged mn3008s... ive had good IC supplies from them so far (mn3007s, 3080s). that could be an option if you want to risk your $$$

ive mentioned this fact on a few forums and being flamed for it but i trust chipforbrinas more than hkss. even though im happy to buy a lot of non-IC components from hkss i belive the IC they get are not checked for authenticity.

I have built two analog delays around the MN3208 and MN3205 and am interested in the difference of MN3005 vs MN3205 with respect to sound quality.

Can someone shed some light on actual real world sound differences?

That would be so great.
I'm not interested in long delay times, therefor I use digital ones.
But I'm very much interested in having an 1V/Oct. Karplus-Strong machine (or two Laughing ).
So the possibility to insert MN3006 (128), MN3009 (256) or MN3004 (512) also would be a hit.

As far as I know (rumours, rumours ... Very Happy ) CoolAudio IS Behringer.

Another rumour, I heard, is that they sell only to resellers in huge quantities (1000 pcs or so), but that may be wrong information.

As far as I know.... Laughing You are right.


Besides CoolAudio, there is another manufacturer of BBD. "The Shanghai Belling Co."
Thy call their producs BL3207 and BL3208. --- Low voltage type (5-10V), like the MN3207/3208.
You'll find the datasheets on ther homepage: http://www.belling.com.cn/col89/col90/article.htm1?id=1567



btw.
Here http://www.sdiy.org/BBDHell/ you find a BBD-Manual from Panasonic.

Right. The question is, how many of these are around today, and will be around in 6 months, when such a PCB could be finished?
I'd hate to invest 2000 Dollars in a PCB run and prototype, and then sit on the boards ...

JH.


I've been offered 100 MN3005's for $18/piece. I'd have no interest in making a profit but I'll get them if there's enough interest and this project looks like happening. ??

have you the possibility to check if they are good ?
I think the bigger problem than if one costs some dollars more or less is the risk to get bad ones.
On a big order thats then a real problem
I would take up to 8 i think, maybe more if i take also for other Friends

You won't have any problems getting rid of the chips. If the project supports more than one BBD chip, I'd get more than the 2 boards, but I would certainly take some of the MN3005s off your hands as well. I have a couple of modules that use them and having some good backups would be wise on my part. So it looks like you'll have no problems there.

I'd be taking 6 to 8 MN3005s myself, though I would take only what I need if the demand for the chips for this project eat up enough of your (still hypothetical) supply.
