**** your good man.... yeah that loose red wire was to the standby switch. I accidentally broke it loose when I was lifting off that small board to put the big capacitors underneath it. I soldered it back into the hole and everything's good to go.

The blue ones are replace in the amp. Here are the new ones :). Turns out the problem was a bad el34 power tubes even though it was a brand new one ordered from Mesa.

I asked Mesa Boogie about burning in the capacitors and they said no I did not have to do that. I think that really applies to Old amps that have been sitting for a long time.

I visually inspected the tubes and they look fine and I don't see any Scorch marks on the tube sockets. But I think you're right from everything I've researched it sounds like this only happens due to a bad power tube. I'm going to put the app back together and put in a new tube and see what...

Hey guys I've got a 1985 black stripe Mesa Boogie Mark III The amp was working fine but since the electrolytics are 33 years old I went ahead and ordered a set from Mesa Boogie. Yesterday I changed two of the big 220uf 300v filter caps. I also changed one of the three 30uf500v preamp caps. The...

Seanboy How different does that 105 sound compared to the standard Mark 3 Transformer? I swear to God I can't believe there could be another amp that could sound better than the early Mark 3 black stripe.

Can you take a picture of your markings and please post to this thread?

It is a tall and narrow head. There is no speaker in the head. The head actually came with a wicker combo case. I am starting to think this is a custom case. It has a switch on the back that lets me run Simul Class (2xEl34 and 2x6L6) or Class A (2xEL34). How many watts is this? 15w/75w or...

Excellent thank you!

Hey guys I'm new to the Forum. This weekend I was at a local guitar shop and in the corner I saw a Mesa Boogie Mark III. I plug the amp in and tested it out and immediately purchased it. It's an early model 1985 Mark III that actually has the C+ Transformer as denoted by the + mark above the...
