MARSHALL JCM 800 MASTER MODEL MK2 50w LEAD 2204 GUITAR AMP HEAD 240v. GOOD TO VERY GOOD CONDITION. USA EXPORT MODEL.

MADE IN THE UK 1989. SERIAL NUMBER X19534. QA STICKER CONFIRMS 1989 BUILD. ORIGINAL DRAKE TRANSFORMERS and CHOKE. PREAMP TUBES 3 x CHINESE ECC83M. POWER TUBES are 2 x SOVTEK EL34. BIASED AT 445PV and 30mV.

THERE HAVE BEEN MODS ADDED TO THIS 2204 over TIME. THE FIRST SEEMS TO BE A SOLDANO 6C10 V2 valve MOD in 1991 as inscribed on the chassis by J.LONG. This looks to have been later removed and the V2 12 pin socket replaced with a 9 pin socket back to 2204 spec.

NOT a TECH. I will list the MODS that I have observed and researched online.
