Title: Need some interior pictures
Post by: assquatch20 on December 04, 2019, 10:28:23 PM
Hey there, my buddy forgot to take some pictures disassembling my amp and now doesn't remember where the connectors from board to board and such go. If anybody would be willing to post pictures or any assistance with the layout it would be appreciated.

Hey assquatch20, As you posted this in the T100s section I assume this is the amp you need/want pic for.  Not that many of us have a T100s (they are rare beasts), but MJMP does so he may be able to help you out.  Mean while, have you checked the schematics ?

I appreciate the help. I'll try to contact MJMP and see what can be done. I've got schematics and I've given copies to my friend but I'm trying to make it easy on him so it can get done.

From what I could find on the schematics

power supply pcb
K1 ==> power transformer
K2 ==> standby switch
K3 ==> amp pcb K1

amp pcb
K1 ==> K3 power supply pcb
K2 ==> power transformer (filaments)
K3 ==> feedback output transformer 1
K4 ==> output transformer 1
K5 ==> inputs from vol pots
K6 ==> feedback output transformer 2
K7 ==> output transformer 2

My tech buddy appreciated this very much. It's (mostly) back together but I haven't got to test the thing out yet. A little nervous. He lost some of the mounting screws for the left rack ear so I've got to pull a bunch and figure out what sizes I'm going to need. In trying to do so at his shop I accidentally undid a ground which was pretty annoying to get back on. After that, I slapped the cover back on and decided to come back at it later. On top of that I think a tube retainer popped loose again as it makes a faint rattling when I'm playing through other gear nearby.

I'm unsure if the amp is actually fixed as well... it's been frustrating, to put it nicely.
