New member, need advice on a M 1.01t repair

Recommended Posts

Hello everyone , glad I found this site.  I Find the topics very interesting and informative. It's winter here in Ontairo, Canada. So i have until April/May to get the maintance and upgrades done

on my sound system. The rest of the time I do Astrophotograghy, which is challanging at times. My current system consists of the following


Turntable-Techinics SL-1310MK2

CD Player-Azur 640c (analog L/R section disconnected), tube buffer from GlassWare ACF-2(6SN7 tubes) is what I use for the cd player analog selection replacement . It was built by me


Preamp-Aikido Stereo Octal  using 6SN7 tubes( currently building a dual mono preamp-Aikido) and built by me

Phono-Tetra Sans PS Phono preamp and built by me

Amplifier-Bryston-3B st

Speakers-Martin Logan Aerius i


My goal is to switch to bi-active  crossover and using the 2x M1.01t for amplification.

One of the M1.01t channels is defective. I have already posted my problem-got a responces (very quickly i must say and direction)

So I am resoldering the input pcb now then I test

I have already have been reading up on the topics here to help me plan the change over.



Take care

Many Thanks

At this present momont the audio system is having a overhaul.Amplifiers (carver m1.01t being modified). Aerius, back binding post-replaced. Aikido Preamp, updated(actually the parts arrived today).

So pictures will have to wait. Just finished the thump fix one amplifier getting to test. then on to the next mod-idle bias pivot mod.

Thanks everyone for weicoming me.

i've been modding my M1.01t, fixed problem with left channel (cold solder joint on main board), speaker post replaced, input pcb resoldered/cleaned.

Next is the bias mod, small electrolic capacitors replacement, power capacitors replacement, and setup and test



1.  I would like to replace the large barrel diodes with a bridge rectifier .

    What is the part number of the bridge rectifier used ?


2. installing a AC EMI filter

    type of filter and where would the gnd connect to, i'm guessing chassy if so would I

    need to isolate the power gnd from chassie gnd and install a gnd lift switch ?


This site has helped me out on alot, by reading other post, and how they ended up fixing there equipment.

Still learning to navagate around the site
