I received this message by e-mail this morning:
Hello there Steve!
This is Jan Tangfeldt from Sweden.
Sending you two schematics (AutoCad), 1 original and 1 with modifications made on Eric Claptons MM HD-130, plus a slight tonestack mod I made myself.
I�m using a 210 HD-130 that I bought back in 1975, and never have had any trouble with it. I�ve tried a lot of other amps, but I�m always coming back to this one.
Welcome to visit our homepage:
I converted the AutoCad drawings to CorelDraw, edited them for clarity and color-coding and created PDF files. You can find them here:
Eric Clapton HD130 Mod
This looks like the schematic I sent a few months ago to somebody in Sweden that was from the hand altered schematic sent to me by the MM R+D dept in the 70's. I worked for a music store at the time that sold MM's. If that's the same info, I'm glad somebody cleaned it up and made it more clean. May not be the same guy but it is a funny. Mike.
What goes around, comes around! I've lost count of the times I gave someone some information that wasn't commonly available (or even unique because I generated it myself) and several months or even YEARS later that information is presented to me in a completely different format but most times with EXACTLY the same wording (I recognize my own writing style) and drawings!
The internet is the largest information pipeline so it figures that it backs up or flows around the world in a circle until you see what you flushed in the past, usually changed or re-digested a few times in between!
I know the feeling-isn't it cool!
I rather enjoy seeing things wander about on the net... it is my feeling that if you don't want something distributed, then either mark it as proprietary, restrict its distribution physically or don't give it out at all!
However, I like getting good info for free so I don't mind giving at least as good as I get!
