Title: MXR Flanger build coming along / Components Needed
Post by: Bainzy on March 10, 2006, 03:26:58 PM: I'm building the original version, with the Reticon SAD1024A bbd chip. I'm trying to get some pictures taken of it in progress but the camera seems to be messing up.

[I'll post the picture here when it's uploaded]

Soldering this is hard - the soldering pads for each hole are very small and the soldering iron doesn't have a small tip. I'm getting there, albeit very slowly. I'm trying not to rush this project. I sucessfully managed to get 15v supply to it from a 9v adaptor, by using a MAXX1044 charge pump to get 17.2v, and then installing a low-dropout voltage regulator to make it 15v.

By the way:

Does anyone have a JRC4558 (or rc4558p) chip, and 2 electrolytic 15uF capacitors? I'm building an MXR Flanger (which will be posted on the tech center by the way), and all I need to finish the kit is these parts.

Smallbear (or any electronics manufacturer that supplies hobbyists in the UK) don't have any 15uF polarised electrolytics, and either smallbear sent me 1 less rc4558p than I ordered, or I lost one while unpacking my order as I'm definately 1 short than I need.

I could trade original MXR factory schematic and board layout sheets for the parts, or I could pay by paypal I guess.

Have many 15uF different electrolytics

I found farnel brillant for componants except for bucket brigades and some opamps.

NExt day delivery and free postage, without any need to open an account.

"The Company reserves the right to charge a handling charge of £3 on all orders under £30."

I don't even have £20 in my bank account to order £20's worth of electrolytics, lol.

i have plenty 4558's pm me if you need any,
Nice going with the charge pump btw, handy for those vintage 15v-18v beauties,

Post by: HTH AMPS on March 12, 2006, 05:32:22 PM: you should be able to get 4558s from Maplins, as for the 15uF cap - the 10uF and 4.7uF in parallel suggested earlier is the best way to go.

:twisted:

Post by: HJM on March 12, 2006, 08:50:57 PM: I need to order some bits from Farnell this week or early next week, I can add to it if you want to get your caps.

Post by: Bainzy on March 13, 2006, 12:08:32 AM: That'd be awesome - I went ahead and ordered another 4558 from smallbear but they don't have the 15uf's. If you can get 2 15uf polarised electrolytics that'd be kick ass, just work out how much they cost and I'll paypal you the money for them and postage.

Post by: HJM on March 13, 2006, 07:38:45 AM: No problem, if you go to uk.farnell.com and pick out the ones you want, I'll get them ordered. PM me with the farnell part number.

Sorry only just joined the forum, (like your MP3's great playing by the way). Two sites that can help you get the parts. If you don't already know them..

Two German sites, they will ship to England no problem. I`m now in Switzerland but used to use them all the time, used to take about five days from ordering for a small number of parts, most of the time no customs duty....... If you have a problem you can ask questions, both site run be great guy. The Forum on musikding is in German but you can post in English, and you will get replies

Post by: HTH AMPS on March 20, 2006, 11:09:55 PM: the prices on that Banzai site are really good too - gonna have to check them out soon.

:twisted:

Post by: Bainzy on March 21, 2006, 06:04:13 PM: That Banzai site does look extremely good - Ive worked out if I do a TS-808 clone with the BYOC PCB I won, it'd cost me less than £20 to build it using parts from there (all of which they have too).
