Would it be possible to convert the MK1 to a MK2 ? I know the MK2 has different output transistors If you have to choose between The 05 vs 07 mk1 ? Also to take advantage of the MK2 and 05 amps, do I need a preamp with the same frequency response ?

So in the end, the MK1 version will last longer and wont oscillate

Are the MK2 version of the amp, much better than the originals ? The only difference in the spec is the frequency response Frequency response: 1Hz to 50kHz MK1 Frequency response: 1Hz to 600kHz MK2 Should I be worry about the Frequency response ?

I just got a Soundcraftsmen MTX S860 amp, I did some research and someone tested the amp Here are some numbers at 1204 180 watts what do you guys think ?

I was able to get a rotel rb-991 for $100, but 1 channel is out, the amp is with my tech right now https://www.hifiengine.com/manual_library/rotel/rb-991.shtml Can anyone comment on the design of the RB-991 and if it is better than the 1070 ? Full review with numbers...

I did some research on the P-2200, and that particular Yamaha amp is the base for the M-2. Here is the professional review of the M-2 https://www.hifinews.com/content/yamaha-c-2am-2-prepower-amplifier can someone review the lab report and check if the numbers are good ?

Maybe in the future, @restorer-john what do you make of the P-2200 ?

The hum is coming from the speakers

Maybe is the wrong topic, but I got a Yamaha P-2200 mint condition for $70. Working fine so far, a bit of hum when I set the input attenuators to 0db, is that normal ? Can the P-2200 be used as home audio amp ? Some pics of the inside Here are the charts for the specs

Some pics of the amp

what are the output transistor ?

I was too late, the guy sold the pair for $100, but he sold me a nice Yamaha cx-2 preamp for $100, not bad at all. I was able to get a Kenwood MX-5000 for $60, not much info, it was the last stereo amp from Kenwood. Any comment on the design and topology ? waiting to arrive...

Are they specs any good ?

I was offered a pair of MA700 Mono Amplifiers, I know they were designed for 5.1, thinking about using for a stereo set up. There is not much info out there Here are the specs
