All these schematics are from a Jack Darr book. Electric Guitar Amplifier Handbook. I cannot find a download the includes the schematics, just the text of the book which is a pretty good book.
I am going to post here where to download it chapter by chapter. At this site they state that they are going to have the schematics soon? These books go for around 150 bucks so if ya want it,
go to this site and download it and check back once in awhile and maybe they will have the schematics up.
Have Fun

Hi Dragon

Look up top of the page in the menu bar and see Schematic Hell. Click that and explore.




Oh geez, you are WAAAY down there. I am more familiar with Washington DC and Richmond,.

[dragonwerx]

I think there are schematics in that list that are difficult to find? At least they were at one time. I have had that book for about twenty years.

[Enzo]

Sure, we are always finding schematics. I occasionally have one everyone else is looking for, and conversely sometimes I need one someone else has had forever.

Thanks.

Never understood why NOBODY ever posted the schematic section.

Usual excuse is either "they are Transistor so who cares?" or "they are available somewhere in the Net", both stupid reasons for NOT to do it and reminding me of that HOT girl who whwn I asked her phone number she answered "oh! itīs on the phone book!!!" .... which at least was technically true.

IF you can, please scan/picture them and one by on upload them here or create an album somewhere , at your own pace of course.

IF possible, scan them at some local Internet place because that solves focusing, illumination and parallax problems, aim at something between 1024 x 768 and 1366 x 768 or so, so schematic page at least covers full monitor or is somewhat larger, so small letters are readable.

Save them preferrably as .png, which are always sharp and you can zoom in with no trouble, avoid .JPG or .JPEG which were created for Family/Holiday pictures, excellent colour management but fuzzy, a poor choice for mostly black on white schematics.

Lots of too small, fuzzy or poorly illuminated schematics out there

Take your time, I BET it will eventually become a VERY popular site

[dragonwerx]

I used my digital camera to take the pic of the Harmony H570 that I posted. When I uploaded the pic from the site as a jpeg to my desktop, then opened it from there, I was able to enlarge it and read it with no problem. I could maybe do that once or twice a day, or week, but as far as going to the library and scanning them, I know Dragonworks, and I don't think that is going to happen. Some of the schematics are on two pages which makes scanning harder, probably harder taking pictures also.
If I were to do this, where would I start posting them. I guess I could do it in all one thread?
There are lots of tube amp schematics besides SS in that list.
I am pretty sure there are many more schematics in the book than what I have posted. I would have to check. I don't know where I got that list, I know Dragonworks and he didn't sit there going through the book page after page writing down the amp Maker and Model.

Dang! I thought I was going to get through today without learning anything new
