Here is a pre-owned Marshall JCM-900 Head Amplifier. Featuring 100 Watts of all Valve Power, this amp is a true classic! Made in the England Marshall factory in 2016, this JCM-900 features 2 channels (Gain & Lead Gain). In fantastic condition throughout, this amp has only had light home use. It comes complete with its original Box and Footswitch. I can use the tester efficiently, and can follow the schematic easily. Incidentally, this amp was built with EL34A's the wiring looks as straight from factory, pin 1-8 are joined on the tube the serial number also starts with Z which I am led to believe is when Marshall JCM900 4100 used the EL34A.

Early 90s JCM900 with two channels and reverb on both. A lot of opamps in this amp. They are used for the input and first gain stage, reverb drive and recovery, and for the boost circuit. It essentially has an overdrive pedal inserted into the front of the amp before the V1 12AX7 drives the tone stack. It is a cathode follower in the typical fashion. V2 is a gain stage and V3 is phase inverter.

Somehow I lost my chassis image of this amp and all I have is a pic of the crappy re-soldering job someone did in the past. Ultraman tiga the movie the final odyssey sub indo. This thing had intermittent crackle and it would cut out occasionally. Ghunghat ke pat khol telefilm. After re-flowing many solder connections like these ones it worked reliably. It was also extremely dirty. I'm sure cleaning the pots and tube sockets helped too.
