I just Acquired a Kustom Tuck and Roll K100 8 Combo

It Powers on and some guitar sound does come out of it on the Left Channel, The right channel has no sound.

Amp is kind of loud when turning it on and has some feedback.

I want to repair this amp as its in very good condition.

I need to know where to start I know NOTHING about vintage Amps but I really want to save this amp just because of its history and looks.

I have High Quality images of the boards inside but the Insert Image icon is not working for me Thanks

Now guys I do KNOW how to SOLDER so thats not a problem I'm just not used to these older parts and what to replace them with.

This amp has specific problems that I know you have seen before but I have searched through the boards with little success, I found a few helpful things but there is ALOT to go through on here you guys know so much about these amps and I'm sure this is for sure the right place to be as an Owner of one of these Pieces of History I love the fact its Vintage and has such a nice back story I really need to fix this amp Any advice would be very much appreciated.

I noticed the wires RED BLUE and GREEN coming from the PC1500 where not connected to anything after looking at the Diagram which I can barely read Schematics by the way I concluded where the wires went From PC1500 to PC1400 I soldered them back in place as there was still a piece of REd and Blue left hanging off of PC1400 I removed the old pieces and put the wire back through like normal while puttin green back into the only other hole left above red.

The Green wire is going to the Power Light

When I turned it on now the Right channel has sound and its Louder than before, the left side has no sound.

the Power light was not coming on, but all of sudden the Light came on and the amp built up this humming noise which kept getting louder so I turned if off and back on and it keeps doing this.

I am lost PLease Help ! Thank You.

Welcome to the place.

If you disconnect the three wires that you connected earlier what happens, does the amp no longer hum?

With those 3 wires disconnected the hum that gets louder is not present but then the left works and the right doesn't and the volume is lower very low actually

From what I could see in the one photo that I looked at, there has been some work done to the amp. The photo service that you use locked up my browser, so I can't try looking again until I get home tonight.

It's pretty obvious that somebody cut the wires to stop the amp from humming. So you will need to test each of the separate sections of the amp and find out what is working and what isn't.

What electronic skills do you have? What test equipment do you have available?

Went ahead and changed a few things now the right channel is loud almost normal sounding and much louder than before Don Thompson pointed out some parts that were replaced that were wrong parts So I changed one of the Transistors that was Wrong with one that works much better, and removed some kind of wonky thing that was not even supposed to be there in the first place fixed something.

The real problem im having now is the left channel is low and dirty, and when I touch the Treble on the Preamp which is I believe Pc1400 Board it makes a REally loud HUM REALLY LOUD until I stop touching it that is weird and freaks me out any suggestions?

Also if any of you techs has a facebook I could talk to you on there and provide instant pics and video of what the amp is doing in real time Thank You Very Much for any help at all
