The Peter Daniel tribute amp

[tiroth]

Peter,

I've been very impressed with your elegant, austere designs. This is my rendition of your acrylic GC; I took what I felt to be the general feel from this amp, rather attempting a carbon copy. I am still struggling to accomplish in weeks what you can in a few days.

Here is something slightly more original. I am still deciding between black and natural for the vents. These are good for a full 40-45W, although I intend to use them as tweeter amps and use no more than 8-10W.

I need a better camera. The monoblocks are transformer-coupled. There is no input coupling cap, although there is a zobel network on the transformer secondary.

Here is an ugly little amp that I built as a center channel monoblock. It sits out of sight and gets the job done; I did use good parts for the internals. Most of these amps use Panasonic FC supply caps, Holco (NOS) resistors, and Alps pots. I did some experimenting with Dales. The blue coupling caps are ERO MKP1845...very nice.

And finally, this was my first GC, built to test the chip amp waters. It uses junkbox parts and does not sound as good as the others. I was impressed enough though to try to improve the design.

This makes a nice computer amp at 15W/channel.

Interesting,
Your first amp has a wooden case.
Peter’s latest amp, also wood. Hmmmm.....

What kind of input transformer did you use in the MB-GC? Is that a motorized pot next to it?

Nice work. Interesting progression.

What is that, a power transformer with the dual primaries wired up as primary and secondary windings?

By the way, nice work!

i like Natural for your vents choice... looks very clean.

superb work
