Amek M2500 Build and Support Thread - the sequel
« on: January 06, 2010, 10:46:15 AM »
The old M2500 thread now has a mysterious defect; you must be logged out to see the content. I don't know why, seems to be a bug. So, I thought I'd start a new thread. Please post if you are building this, have any questions, or further information. Log out and see the old thread for more.

Basic build info can be found here in the wiki.

I have attached an Input Amp diagram from an AMEK blue TAC 1682.

It has a Sowter Input Transformer  followed by a NE5534

I have heard that is a Langley design very similar to the M2500 Input Amp section that also has a Sowter followed by an NE5534, and from around the same time period, right after AMEK started TAC.

I have not compared but if anyone has an official schematic of the M2500 Input Amp,  or definitive design history relating to TAC, I would love to compare notes.

On the TAC 1682 Schematic the channel pcb is labelled GL 163 (george langley?)

The TAC 1682 is a very decent sounding console, a sleeper..


I catalogued some of the old design drawings that I have and I have to check whether I have M2500 input diagram.


GL stands for Graham Langley.

In terms of TAC's design history, the TAC company had a completely seperate design team from Amek. As far as I know Mr Langley does not like transformers but I will find out about that particular module in a couple of days.
