Might be better off moving this to the "for sale" section....

Why does your eBay ad list them for 80 but, your ad in the For Sale section lists them for 15  ???

BTW.... links to eBay items in the For Sale section MUST BE fixed price only. It appears that your link is an auction.

Price is different!1 piece is expensive now - see FARNEL.com is the same... or can you buy from China  ;D or Hong Kong!!!-best quality!!!
Or can you wait 2 more days and buy my 8 pcs. for 80€! :icon_wink:

Hope its ok to open this thread if not... my apologies.

I have been doing this project on and off for the last two months.  I  finally have got to the stage of testing it,  It does actually work which really surprised me...but I still need to get it set up properly and then box it.  Here are some pics of it. I did make a slight alteration...  the individual boards can be seperated by the plug I made.   It was a great achievment by Tomas and I am grateful to him for doing great work on this and the EM3007 , EM3201 etc.

It has taught me a lot about Flangers, I have also built the Lovetone doppel ganger by Lacesensor, that was another great build. I just love the challenge of these great  60's pedals.

I will be doing the EM3007 as I have a few Mn3007 chips
Thanks
Mike

 Congratulations, Mike, and thanks for the pics! I'm glad it is still possible to get TDA1022 chip and matching slide-switches somewhere :) Good luck with the final adjustments and boxing, do not hasite to post final state then and some soundclip too ;) T.

Nice work Mike! Glad to see another build of this versatile flanger. This unit has been on my pedalboard since its completion in '09.  it is very easy to dial in on the fly and covers many flange/chorus/vibrato sounds quite nicely.
Nice to see you Tomas!  :icon_biggrin:
That's where it's at.

Hi Tomas, thanks for your encouragement, I still have measurements to do on the build.. and the enclosure. I want to make sure it all works .  I found this company on the web which has the switches, so for anyone who has been put off building this pedal in the past the address is here...they are a good price as well :)

Thanks Dave, yes I was enjoying some of its sounds this morning, It is similar to Tomas demo at the begining but as the demo moves on and the flange becomes more lush...I haven't got that same sort of swell. Anyway I will take all volts readings  of IC's  and get it sorted :)
Mike

UPDATE
I  spent most of today doing checks on this build as I new it wasn't right....I was relieved to find the problem, and felt a bit annoyed with myself...as I am an oldie I can blame my ailing eyesight, I had a TL074 in the socket instead of a LM324N. Yes they are both pin compatible and actually work but they have a lower vol output and they don't have that lush flange I was telling Dave (biggrin) about. If you have built this please try it you will see what I mean.
Anyway..it now sounds like it should. LUSH!!!

I have a pair of those TDA's that I scavenged from an old bass head that a friend gave me. I'm thinking this may be the project!

Would these switches be ok?

Hello all,

I plan on building this effect, and I've been studying the layout and schematics very hard for the last 3 days. But I need some help. I want to utilize the clock buffer (IC2), but cannot figure out where to wire the pads to. I'm assuming that instead of using the buffer jumper wires, as defined in Tomas' layout in the PDF, I need to connect those jumpers from IC1 & IC5 to Q+in, Q-in, Q+out, & Q-out. But what goes where? I noticed Rasvan used the 4049 buffer, but I don't see it wired in his pics.

Thanks, Jeff

Hi, correctamundo - buffer inputs (Q+in, Q-in) go to clock generator output (IC5, pins 1 and 2), buffer outputs (Q+out, & Q-out) go to BBD clock signal inputs (IC1 pins 1 and 4).

My pleasure, good luck with the build, keep us posted! :) T.

Thanks Tomas!!


One other question I had. For the TDA1022, filter cap, that goes on pins 5 & 9, right?

This is going to be an exciting build. I really appreciate all the info that you have given on this. Will I be build # 4?  :icon_rolleyes: I can't find the slide switches here in the US, but, I can use other, and use jumper wires like Ransvan did..

Thanks again for your help, Tomas!

from this thread. page 4/reply 68:
QuoteIf you are unable to locate a source for the 4 switches, Small Bear has a workable substitute:
http://www.smallbearelec.com/Detail.bok?no=495
Not an exact fit , but if you change the artwork for the buffer board a bit it will fit/work.
get the switches then adjust your pcb artwork.
filter cap for the ps bypass on the tda goes to pins 9 and 16
That's where it's at.

Thanks for the pin info Dave.  As for the link with the sub switch info, I looked there already, but that thread is broken. I found some others though.
