Anyone have any luck contacting Dr. Leach
Has anyone had any luck in contacting Dr. Leach recently? I'm trying to order some low-TIM boards but havn't recived a response after sending a couple emails to the account listed on his web page.

Is he still alive?.... he was reasonable old in the seventies, now 35 years older.
Did they have some facility to provide boards, some Leach center? i am in doubts! he still alive?

I contacted Dr. leach about three years ago because I wanted to reference something on his website in an article I was writing. He responded promptly and granted permission. He was alive in 2002 and he, or someone, keeps changing the website. I bought some items from him in the 1970s, but he may no longer be in the parts business.

It could be that he is busy with the beginning of the new semester - darned job and that sort of stuff. :D

It is good to know Marshall Leach is healthy and already working
So, thanks by the information

He responded promptly to me when I ordered my boards. But I guess that was about 2 years ago (and they still AREN'T done!!!) If only time would stop flying.

Both boards are pretty simple. If you can just roll up your sleeves, you can start doing your own. If you are looking for the super leach, I happen to had laid one and I can sent you a pdf file. I am still waiting for my purchase list to grow big enough to share the mailing cost (I am looking for 2n5416 nd 2n3439)

Hi Kelly

Yip the original Leach boards are quite easy to make yourself as they are only single sided. But wiring really is a pain as well as mounting those T03 Transistors on the heatsinks.

Take a look at this thread.

Unfortunatly the board group buy has already happened - but I think Jens has some of the 10 Transistor version boards still up for sale - otherwise you can get a production house to make you some from the gerbers provided by Jens. Take a look at my amp in the link in my signature line - you will see what I mean about all the wires!

I am in the process of doing a build of this new version myself and have already done the version currently on Leach's site. It sounds very nice and quite different to other amps. Natural is how I it. No fake tizz of boom. I consider that as destroyering the sound ;) but we all have our preferences.

Bigpanda. There are "generics" of these done by a company called NTE

I contacted him about two months ago. I originally enquired about his boards, received no reply so I then joined in the group buy on the Smaller Leach by Jens. After I ordered the boards with the group I got a response from him and he indicated he was very busy and was catching up on his email.

If anyone wants to consider swapping a pair of his boards for a pair of Jens version let me know I might seriously consider it since I have the TO3 heatsinks sitting on the shelf and don't really want to acquire more heatsinks for the flat plastic ones.
