Hello all,
Finally got this back from a "professional" after 2 years of waiting. 
When I started I didn't realize how big the output trannys were, so you will need to re-case this. :eek:

Boards and parts from the group buy way back from from I don't remember who supplied them.
Cinemag input and output trannys also from group buy way back when.
JLM ACDC power supply
Amveco toroid
Elma pots.

I trust you guys to help me with a fair offer because I have no clue what to ask.

Paypal accepted.
Free shipping within continental US
everywhere else we will have to figure out the cost based on your preferred method of shipping.

hopefully google drive pics links work...

When I started I didn't realize how big the output trannys were, so you will need to re-case this. :eek:

Why? The lid won't go on?

I built a pair - these are great preamps! 
 
it does but i had to cut a hole for the output trannys to poke thru

it looks dumb, so you dont "have" to rerack it but prolly should.

can you give me a suggestion on an asking price?  i now ive got about 300-400$ into itvin just parts
 
I don't know on the asking price - probably the cost in parts if you want to sell it here to another DIYer
My impression is if you want anything more than the cost of parts it needs to be a complete pro build and listed elsewhere.
Just my opinion though
 
It's a great circuit  [ I have 4 built that I use, built some for others ]
for my quad , I bought two Jensens and two Cinimags ,  I'd have to open it up, to know which but  the Cinimags may have been a tight fit
but it's a physical thing  [ they handle more output  ? ]  So I have two chs with output iron and two chs unbalanced  out
if anything the unbal sound cleaner ,  but I use both . cut a hole in the top or file off the  bobbin ?

It's the problem with the diy stuff , it's hard to charge for your time ,  so decide on an amount you'd be happy with worst case
 
The electronics and wiring look good but the price (or current value) of parts is probably the most you can expect.  Judging from the pictures of the current state of your MP-2MH build: it's still not technically finished (as the next buyer still has to spend more time and money into your MP-2 project to complete it).  The enclosure is likely where you have to take a loss.

The pdf of the the official Dan Kennedy/Great River MP-2MH enclosure dwg can be found in the thread for the MP-2  (and has all the dimensions you'll expect from the Collective Cases' version of the  MP-2 enclosure).  The only difference with the Collective Cases version uses the sizing for only one pair of XLR holes and that fact there's no silk-screening or labelling. 

The more you can reduce the work for the buyer: the more reasonable it'll be to ask for a dollar value closer to the price (or current value) of parts (depending on whether you include a proper MP-2 enclosure or not). 

Expect your MP-2 to sell quicker (and for the most money) if you decide to exclude the current enclosure (and sell everything else) or installed into a proper MP-2MH enclosure.  The most you'll expect in every case is the price (or current depreciated/increased value) of parts.


 
part of the problem is without advertising, people may not know what a great circuit it is , and like most  d.i.y.
So maybe explore parting it out, depends how quickly you need the money
it takes longer to sell more individual pieces, but the Xfmrs and boards could get you most of the way there,
also postage without a large case will be lower,
maybe post asking for offers or opinions or parts , good luck

Bump for someone should buy this!
 
its finished.
based on what yall are saying, i think ill ask 400 plus shipping

thanks for the help fellas!
 
"!!BUYERS BEWARE!!"
I paid for this mic pre amp on Dec 25 via Paypal and have not heard anything back from this guy since. I have contacted him several times here on Groupdiy since then and gotten no response! Even emailed him and still...no response!
Just a friendly heads up for my fellow DIYer's.
:mad: :mad: :mad:
Shame on you Josh!
