Recent clip recorded with the amplifier from this thread. Still sounds good to me.

Re: New HRM build

I checked in my attic and that computer is gone. I did find my Mac SE and it boots up! I also found my Quadra 700 too.

At this point I think all my schematics that can be edited are gone. I do have PDF or screen shots of most all of them. Of course these can't be updated or edited.

Re: New HRM build

This is the un-finished layout. Probably never complete it because when it imported, it put everything (even every letter) on a separate layer; 648 layers in all. :(

Re: New HRM build

My schematics are going to be a bigger headache. I can't seem to open any of them, on the old computer with Snow Leopard, vintage 2009 operating system. Those schematics were all drawn up on the iMac computer I had in my workshop that looked like this below that crashed from a failed power supply. I...

Re: New HRM build

Another development. I purchased a refurbished 2009 iMac computer from my local computer repair shop with the intention of opening the files used to create this amp as none of the software I used works on my current computer. The way it worked out is that a new graphics card for my crashed 2009 comp...

Re: New HRM build

My current thoughts on getting good tone on this thing is an analogy to film photography. All the older discussion I re-read in this thread might be akin to explaining how I set my 35mm camera to take a picture; f-Stop, Shutter-speed, and focus and film type. But as soon as I want to take a differen...

Re: New HRM build

All the pictures from this thread were on Photobucket which won't show them.
I'll try to re-post some of them.
