Works fine with SR-009, SR-5 and SR-Lambda NB, BTW.

All the SRM1 MK2 are good but the older A and B versions are not only older but were built with cheaper parts. The late C Version was improved and especially the pp with 2 pro bias outputs.

So I refurbished my A version with nice new resistors, caps, and diodes.  I also plan on adding a pro plug.  where would it rate now?  how much of a circuit change was there in the late versions?

Hi all, I'm in the process of reconfiguring a SRM-1/MK-2 and want to confirm whether or not the leads into the transformer is properly set up so that I can rewire according to spritzer's post here: http://www.head-fi.org/t/223263/the-stax-thread-new/5835#post_3902577

 

Am I good to go?

if it was a 100V unit originally, you will have to pop open the plastic top and resolder

the wires. If it was a 240V unit, you will be ok.

post #2167 of 2794

This one's indeed a "100V ONLY" unit, an early revision A. How should I be soldering the leads once I get the plastic cap off?

 

EDIT: Would this (http://www.head-fi.org/t/223263/the-stax-thread-new/23610#post_9623345) be the procedure you're referring to?

Well, I cracked the plastic case open and look what greeted me:

 

 

Guess I lucked out and am spared a delicate soldering job! Am I correct in assuming that all is fine with the leads into the transformer windings and all I have to do at this point is rewire the voltage selector socket as detailed in spritzer's post mentioned previously?

I just bought a pair of Stax DA100M amps from Japan fairly blind. Looks to me like some of the Rca jacks were replaced at some point. Hoping they will be in good working modern condition. I can't make total sense of the Japanese translation but it sounded to me like I bought a pair in good working condition from probably a reseller with 1 slightly bent speaker jack. I bought off Buyee. Would somebody that understands Japanese well mind taking a look at the Buyee link and or the Yahoo link and briefly help me understand how it was described and if the seller seems like he would really know if they work properly? I am just really curious not that it make a difference now. I am thinking they will be amps for Apogee ribbon speakers one day.

I love the SR-407 with SR-507 pads quite a bit more than I thought I would. Is the SR-507 itself any different or better?
