Mr.T found this “Block Logo JTM45” in the predecessor of "The History of Marshall".  He was really impressed with the outstanding appearance and decided to get it. And finally he got it.  Around ’64–’65 made, the fifth generation of JTM45 in terms of cosmetic history.  The thick gold brass piping looks cool!  At the time When Marshall used script logo, this brass piping was discontinued.

Mains and speaker output section.  Really simple.  Around 1964 when Marshall adopted the white rear panel, printed characters on the rear panel started.  It had two speaker outputs because of PA amp.  In those days, Marshall actively manufactured PA equipments which has pure clear sound, non distortion!!

This amp is for PA though, Mr.T really wanted a block logo model and got it.  Actually it distorts nicely with guitar.  The power valves have been changed with Groove Tube 6L6.

SERIAL NUMBER：1014
Mr.T got this from a friend in Japan.  “It does not sound really good.  But I remember I was very glad when I got it because it was the first 60’s Marshall in my collection life”, he said.  The combination with the silver block logo is very rare.  Marshall might built very few units for particular shops only.

The Indicator and knobs were changed.

The inside of the amp.  European version was converteded into American specification and the mains inlet was changed.  Also the power valves were changed with EL34.
