here's some pix: The uploader is piece of crap: Here is the unmodified board. hte mod removes R10, R9, C6, Q2 (Labeled as D2) and moves C8. Also, I changed C2 (aka C4 on the mod schem) from 1000pf to 470pf, which is on the orig U87. If you compare the two schematics, they look a lot alike;

I know I started the 2006 thread, and that project is on hold until the capsule mounts come in which is starting to look like they'll come in slightly before my ship does.... So, in my boredom, i tore apart a 2001, stripping out the transistor output stage, swapping the 2:1 transformer for a...

Check this out: Hammond DR-20 Reverb Tank | eBay I found an article for a DIY reverb in an 1950 something Popular Electronics. The project is vague on the electronics, referencing a "driver coil" with no other description. I guess this is kinda what they had in mind....

Have a Roland AP-7 Jet Phaser. Me and the guitar player went halfsies on this thing back in 1980something or other. Anyway. wasn't working consistently, took it apart, resoldered a wire that had somehow come off the slow/fast switch, sprayed some Blue Shower (contact cleaner) in teh switches and...

Anyone know if this can still be found anywhere or if the guy who wrote it exists in the netosphere? I have teh demo version which can be found different places, but it's shareware. Being able to do an automated punch in has some appeal, and I don't mind wiring a cable for it. I have the...

OK, Starting another mod thread for the masses. I know, it's all been done before. However, I'm taking a slightly different approach and swapping capsule and instead of upgrading the coupling cap --eliminating it. Otherwise, the rest of the caps in teh circuit look fairly decent. I have one...

Check this out. I don't really want one, but this *is* kinda cool: Tascam RC-71 Wireless Remote 22-2 22-4 32 34 34B 42 44 | eBay

Hi, I'm in the beginning of a mic modding bender. So I have a handful of mics I want to A/B as in unmod, then modded. I've seen "Mic shootouts" that place two or even four in a up/down or fourway cross configuration. Looking for opinions on this. I'm not looking for perfect science here, just...

I still have Bigugly Royer Mod boards available. Head Amp and PSU US$21.00 post paid N. America, $25.00 post paid Europe. Toroid power transformers: (N. America only -- 120v/50Hz primaries) 120v:135v/40mA, 9v/500mA (for a G7 PSU) $30.00 post paid 120v:250v/100mA, 9v/2.5A, 24v/100mA (for a D-AOC...

As opposed to 12AX7 (stock) 12AY7 (most common mod) 12AT7 etc?

Hello, Basically rewind or ff slows down to a crawl and then stops close to the end of the tape (depending on which way) or if you start a tape, get about 4 minutes in or so, you can't rewind reliably, sometimes it will start to rewind, or just not move at all if you hit rewind (brakes will go...

First, did you buy the tape new and sealed or used? If sealed or if they are unused and still have the date code sticker on the tape, anything with a 1994 date or earlier is crap, do as above and trash it and admire the nice clean take-up reel (you can't have too many of those really.... and you...

I wanted to combine my FS threads: I still have Bigugly Royer Mod boards available. Head Amp and PSU US$20.00 post paid N. America, $22.00 post paid Europe. G7 PSU boards US$10 post paid worldwide. Toroid power transformers: (N. America only) 120v:135v/40mA, 9v/500mA (for a G7 PSU) $30.00...

There was a short discussion a few weeks back about creating permanent HOWTO files. GroupDIY has a top billed META thread, which contains links to other META's which then link to other threads. E.g. you go to teh META file and drill down to "Specific Projects" click that link that brings up...

FYI: http://www.rmgi.eu/pdf/RMGI-Pyral%20.pdf

Well, I keep checking the site, out of curiosity. The Tweeter page says Gp9 coming "in a few weeks." 1/2" and 2" doesn't say if this is NOS or New production.

Hello, I've never done this before. Recording a fairly large (100 or so) choir. I also don't have the right set if mics, but am acquiring enough parts to build a bunch of fairly basic but useful tube mics (U47 type circuit) which will be done in time. I can't facilitate overhead sdc's so...

Trying to free up space (for MORE GEAR????) Otari MX5050BII-2. This came to me not working, and so I got a working unit and this was going to be my spare. So I fixed it instead. (Power supply problem) Heads in good shape, photos on request. Would like $400.00 including shipping "lower 48" USA...
