Those are production RATs without the FET input buffer. The 10K on the 2N5458 output buffer of production units is well known.lead2203 wrote:ggbb wrote: Changing the FET would not matter. All the ones Ive looked at had 10k for the buffers, My friend had one of the first ones(v1) with the input buffer..it has 10k. You can see 10k in these pics...

You are right. I was in a rush..sorry but the one my friend has does have the input buffer...with the 10k. A friend of his had one so he ordered one too in late 77. He was supposed to get the bud box one like the one he tried ....but he was sent an early v1 .... one of the very first ones....it was one of the first things I tried to make/copy and I used the in and out buffer idea for other things...so that I do remember......the other stuff about it is lost somewhere in my brain.....that was 1979 but I think it was otherwise the same as v1 but with the buffers and a different circuit board. He doesn't play anymore but he still has it..and the other one I made. Ill see if I can get him to dig it out for some pictures.ggbb wrote:Those are production RATs without the FET input buffer.

Itry to avoid speculation,but something like this could have happened:1995 guy whose name is Pat Jankowiak made a list of schematics including two versions of the Rat.(One was the Rat with an input buffer.That schematic contained errors.)He called the collection Guitar Related Circuits.Sometimes later Aron Nelson made a similar list but Arons list had links to the sites where he had found them.He called the list Selected Schematics.The two Rat links had the same warning."This schematic believed to have errors."Later on,Jack Orman corrected the schematic for the FET-buffered Rat and Aron posted that schematic in front of the two links and wrote "Corrections courtesy of Jack Orman."

likable attempt for explanation.
I built that RAT then.. and it did not work took me a while to finf out why.
But,
Considering the time-match (1995) where does the Jamie Heilman archive chime in? the archive you refer to is what I know as the Jamie Heilman archive.
This stuff:

close to painful. All "classic" links are dead. wow! [/edit]

He appears to be a familyman now according to a message from RG .Considering the time-match (1995) where does the Jamie Heilman archive chime in? the archive you refer to is what I know as the Jamie Heilman archive.
I happen to have a zip file from 2000 on my computer - gif as well as postscript files.
So if you're interested , let me know.
Is this a copy of "The Jamie Heilman Archive"? In those days I was busy printing nearly every schematic I could find afraid it would be gone the next day.
I did it at work and unfortunately some guys scanned the schematics.Some of those files were big enough to take down our server.
Schematics that had errors spread like rings of water and can still be found.

Yep, that's the Heilman archive. I guess one of the first things I "found" when doing one of my very first internet searches ever around 1996. Fortunately these are all converted to Gif instead of the bloody postscript that nobody likes but die-hard Unix users.
snofla1900, thanks for the offer but I have em all. In electronic format as well as in the printed version since I, just as Limbe, pressed print immediately as well.
