Every so often, someone contacts me and asks for some information about my plans (presently on hold) to build Melquiades Full-Range or D-Set, and whether I have a list of parts etc. My experience of trying to find a builder for Melquiades has not been overly positive, but I hope, someday I may yet find someone who has the requisite skills (and enthusiasm) to do this for me. I wish those embarking on this fascinating project the best of luck; I certainly envy you!
I do not have a source list for everything, especially the different capacitors and chokes although I did carry out some preliminary research. As part of that initial build phase, I commissioned a parts list which cost me in the region of £400-500. It is in the form of a spreadsheet and certainly easy to email to anyone interested. I would like to add a word of caution though. This parts list is not foolproof (it was not intended for publication) and there are a few gaps that your builder will have to fill in.
I have found this site, particularly the thread where Romy goes through the build of the Full-Range and D-Set Melquiades of immense help and I urge you or your builder (if he is so inclined) to peruse these to get a better understanding of all the aspects of the build.
Whilst my own project may not materialise, I imagine it would be a shame to have the parts list that may be of help to others and keep it to myself. After all, I myself came to the schematics as a gift freely given to all who might have an interest in an amplifier that promises simplicity of design, and an underlying coherence of purpose. I am proposing to all those interested in the parts list for the D-Set (you can of course use it as a starting point for the Full-Range), who are fully aware that I make no claim to accuracy whatsoever, that parts list. For free, of course.
I did forward my parts list to Romy with some queries and he added some helpful comments so unless he has some objections that's the parts list I will forward upon request. I would like to add that when I approached Romy for some assistance with this, although we clearly disagree earnestly on almost everything, he found the time to go over a very long list of stupid parts and commented on pretty much every element where I (or my would-be builder) had a query.
I have a parts list without Romy's comments, if that is deemed the appropriate one I should be making available of course.
Now, what about my hidden motives? Can it be as unselfish as it sounds, or am I working in conjunction with an unnamed party whose services I am trying to ply on you in a very underhanded way? Certainly these questions will arise and you will need to make up your own mind in due course. For my part, I would like it to be simply about giving out freely something which may save people a fair amount of time (and money) and give them a greater chance of bringing their project to a successful conclusion.
Of course, before building D-Set Melquiades, it is obvious that you should consider building Melquiades FR first. I was myself naive enough to think that one could go directly to the build of the D-Set version but let's not talk about my own mistakes for now.
P.S. Romy, please feel free to delete this post if you think it does not belong here or move it to the appropriate thread as you deem necessary.
