Dunlap Clarke schematic as promised.
Well, for what it's worth..... here it is.
This is just the main pcb and does not include output stage, psu etc. It is messy and of unconventional layout as it was hand drawn by myself many years ago whilst reverse engineering it to enable a repair. All the "wires" that seem to just abruptly end and go nowhere are where they leave the board and go to the rest of the amp..... Perhaps someone would care to redraw the rats nest of a schematic so it is more easy to read and understand? From what I recall, there is nothing special about the output stage and it is just a set of the output transistors (used as drivers and on the same heatsinks) driving paralleled sets of the same type transistors (4 each of pnp and npn per channel I think) in a darlington type arrangement. I have no other information. |

Had the smaller amp years ago because I bought it cheap. Not the best design and surely not the best sounding. In terms of workmanship it looked like it came out of someones garage as a project. Your correct about the output stage if memory is correct.

Will someone suggest a appropriate computer program that will BEST make the schematic with? I want it to be as good as I can make it. I have redrawn it by hand and assigned part numbers, but I want to enter it into a computer drafting and or CAD system...
There is one for sale on ebay, it has some very detailed Pictures. the price is starting at about 200 with shipping, I would like to get it but the cost is beyond me today... Thanks for your help. Last edited by Krisfr; 19th April 2010 at 01:48 PM. |

I believe the designer is on here and there is a long discussion about the design... including some examples having been built. Apparently there is more to it than meets the eye on first examination.
