I am opening this up for those interested in getting some boards. I was planning on ordering 20 sets. I will post a BOM later. This is a pre-curser to an eventual balanced version if i like what I hear.
Interested, but as I'm hopelessly addicted to balanced audio and have plenty of 2SK170/2SJ74 it might not be what I'm looking for.
Here is BOM for stereo pair. I can purchase the BF 862 in a reel and match if interested, I haev found that when these things are purchased in qty and are in factory packaging, they tend to be fairly tightly matched. I also have the MUR 860 leftover from a previous GB, as well as some of the Vishay caps, if anyone is interested. It looks like a stereo pair of boards will be $35
Bakanced is very nice. I am looking at a way to make a bridge between two boards, but i do not know if it is feasible in an effective way. I will be doing a balanced version, as I said, if these sound as good as Juma has stated.
I'm interested in buying a set of boards and any additional parts you decide to sell in relation to the LSK preamp.
Hi Buzz.....
I want a pair (x1 stereo set) provided you can arrange for supply and soldering of all sm components. [If not I shall go ttw route.] Many thanks.

The board house wants $20 per board to solder the SMD components. I am hesitant to force all to do so. What do you guys think? If just a few need this help, I can arrange to do so personally for similar price. We will see if there is a consensus one way or the other.
Sounds good Buzz - either way as long as those little zits are in place when it arrives.
Please shout when you need some $s...and allow for UK postage in my case. We'll have to have that pint as discussed a while ago on ZM's looney thread!!

Ill collect after everything is ready to go. Chinese holiday is coming up, so gotta hurry. I would love to have a pint, problem is, when i go to the pub, i usually have to be carried out🙂
A stereo pair would be great! Also interested in getting the smd parts mounted. Also want to buy whatever other parts you are offering, matched of course!
( I just got some SMD boards to solder up, and I've got no proof if I'm up to the task or not.)

I will probably be in for a soldered one with matched parts as well... Buzz.. anyway you could post your PCB layout?
Thanks,
Thanks,
I'm in for a stereo set and hard to find parts for the build. I don't need smd presoldered, but will take it if that's the only option.
are the 2 pairs of jfets paralleled in the input there to allow the use of bl range devices? Couldn't we get away with one bl pair?
I have two suggestions:
Arrange input pairs to allow thermal coupling with zip tie arrangement.
Have a breakup line between the psu and line sections, this would allow to break of the psu section and use a single psu for both channels, for transformers with single secondary.
Ps: buzzforb, sent you a pm a couple of days ago, did you receive it?
