Sweet. Thanks for the part's list, Wonderland! Let me try to fill everyone in on what I understand is going on here at this point after quick PM's from Wonderland and Teekay. Hopefully a summary will help those interested yet very confused (like I was :grin
to get on board.
Tekay is working on redrawing the schematic right now and hopes to have it up shortly.
Tekay also mentioned to me that he is thinking of drawing up a PCB layout for himself, and he would like to include some modifications for switches and the sort. I personally will not have the time to do a PCB layout as I have a big project coming up and am leaving town in the few days, and I just can't be counted on to do it. There was some mention of doing a copy of the original layout. I would personally be fine with doing a modified version of it, as long as the basic circuit and components were the same with basic modifications for some features. IF Tekay wants to offer that up to us, knowing his work I would be very happy to accept. Any opinions on that? Of course there would be a group buy for these.
I've personally got a spare pair of LO1166's so I may or may not need more, we'll see. However, there seems to be another order brewing right now on the Black Market so if you want original output transformers for this, check out this link:

Original Gardner input transformers are still available from Wonderland if I am not mistaken. Otherwise, one can surely use a comparable transformer from Sowter or Cinemag or the sort if you wish.
I personally need mounting sockets for the Gardner transformers.
As far as transistors, that's a little hard for me to call at this point. I know that the transistors are very important to the sound, but how the newer ones from Digitron quoted by Wonderland will compare to the originals I have no idea whatsoever. Perhaps others with more experience in this realm can comment?
There was also a question by rascalseven about the quality control specs of those said transistors and their consistency. Last we heard this was being investigated by Wonderland. If we can find a batch of original transistors, that would be great, but I for one have no idea where to find them. I would be nonetheless content with using the new Digitron germaniums if they spec well.
The inductor needed is a VTB9042 from Carnhill - 100mH / 200mH / 300mH / 600mH / 1H . All those interested, we should organize a group order for them. I suspect that once a PCB layout is decided upon and finished, that we can start an order for this and other things.
Capacitors are mainly electrolytics which can be ordered individually and mustard mullards which I know nothing about. Perhaps a group buy is necessary, I don't know.
Switches and pots have been spec'd, but I'm not sure where to go to for the switches. Can anyone locate them? The pots should be fairly easy to find.
Wonderland talked about already having a front panel layout and possibly printing out racks if the interest is there. Some may or may not be interested in that depending on where you live. I'm also sure Purusha would jump all over printing some up if we could put an order for ten or more together. His prices are always very fair and usually the best I've found. Seeing a layout then would help people decide on that one, however, that's not so critical as many people will come up with their own layouts.
If a source for original knobs is found then great, otherwise I'm sure people have their own ideas for what they could use.
I would be willing to act as a point-man for group buys for inductors, transistors, switches, and other critical parts if a significant discount is offered for a bulk buy. Basically, IF others help me source the parts and finding out prices, I would be willing to deal with keeping track of the money, putting in the orders, and with shipping out the parts, perhaps as a kit of sorts if it works out that way and doesn’t get too huge, which at this point it doesn’t seem it will be. I think that will be the best way for me to help with this project. I will be in the States for the next six months or so, so please keep that in mind if we want a separate Euro point man. I'm doubting there will be the interest for that however. Also, I am about to start a long and tasking project, so your patience and understanding with any delays will be necessary, but I would like to help out however I can.
Needed parts are listed above this post. The next step there will be for someone to come up with a complete BOM once we have a schematic and PCB layout.
So the big Q now is who is really interested and what do you want for an EQ? Do we need the PCB to be an exact clone and if Teekay does decide to offer up a PCB of his liking that is not an exact clone as far as layout is concerned, are you still interested? I would like the EQ to be as extensive as possible in the realm of a 1053 or the like within reason, but would settle on whatever was able to be specified and sourced. That is not a deal breaker for me and an exact clone is also not necessary in my opinion. Anyone else have an opinion?
Hope this summary keeps everyone interested up to date and ends any confusion about what is going on with this.
Cheers,
T
