The 3.3 nF cap from the 16R OT tap to the presence pot, is this parallel to the NFB coming off of the 8R tap? Do you have a schematic? No, my NFB purple wire is connected to 16-ohm tap, and I just put the cap in series with the purple wire to the presence pot. It is not in now, but I think it would...

I have been resurrecting my original JCM2204 as well, and I have been through many of the changes as the OP here. I found the treble bleed cap (I still have trouble with the names of each part, sorry) that goes between pins 1 & 2 on the MV is necessary, if I remove it MY amp gets very unsteady - osc...

It has been a long time since I posted here, so I thought I would drop by and show a few of my latest projects. I am now using a pedal board where the majority of pedals are self-made. This below is a distortion pedal using red LEDs for diode clipping. [img:408:640]http://i1304.photobucket.com/album...

So, I am not sure, but I think you are saying the aforementioned changes are part of the silver pony layout. Is that right. That seems to "jive" with the preface here at my favorite site: http://tagboardeffects.blogspot.com/2014/07/klon-centaur-silver-edition.html Here they note a couple of swapped ...

Reply to PlayOnIt about the KlonE changes... I don't know if you noticed, but the thread from another board that you cited for certain changes to the KlonE schematic (which I went and read) has now been taken down! Is it possible someone did not want those changes "out" in the public domain? I had a...

Playonit - I read the threads, but I would really appreciate it if you could get a little more specific and post the changes here. (with the specific R numbers, possibly). My KlonE comes from a guy who told me he de-gooped his own Klon back in the early 90s. However, while I have not compared them s...

Anyone ever struggle with the LED - CLR relationship? I could never get an LED with a following CLR (connected to cathode) to light up. Finally, I got in an argument about with someone online, and tested it six times on my breadboard and was convinced I was right, that it couldn't be done. Only afte...

Thanks playonit, I will look at the =KlonE changes you noted.

Looks like you used those vintage transistors Ge Darlingtons - were they hard to find or work with? I have been making pedals myself lately but just spent two full days on a dual FET design with a power pump that I never got off the ground - very frustrating. Here is my first build - a KlonE [img:10...

Thank you all for your help. I tried going +9 - |>| - CLR - GRND. but it just never worked for me. Not sure why. Now I am wondering..... I see another way to wire this PCB so the CLR comes before the LED but that would mean bringing +9 right to the foot switch PCB. Does anyone think that could cause...

Thx - I got it to work, it's 2.2k but I have another circuit problem. I have a small PCB for a foot switch that has a space for a CLR... one leg of that CLR attaches to the LED - and that's all I have. So, I put in a 2.2 CLR and a 2.1mm red LED in the PCB attaching the CLR to + of the LED. The neg l...

what size resistor do I use for a 2.2 mm (tiny) LED?

Nevermind - I got it 2.2k - but I have something else making it not work. thx anyway.

Take a look at the way I got ripped off a couple weeks ago: This listing for a " Peavey Jack " made by Switchcraft (this is NOT a switchcraft issue) - the part number is "12B" - so I though I was buying package of 12 connectors for $12.99. I received ONE connector - and there was a handling charge -...

I just got a huge shipment from tayda, too. I had it sitting in my shopping cart for a week waiting for them to post a new coupon code. Yeah - an amp. I do want to build one. I would like to build a good one-channel amp that takes pedals really well. I like a Marshall sound, so I am thinking a 2204 ...
