A1970 Marshall 1986 Bass Amp was brought in for a constant problem of popping HT fuse. Some maintenance and modification of secondary wire for negative voltage. Tube testing
That amp is also a GREAT guitar amp..Years ago the bass player in our band had the full stack..He left it at my house where we rehearsed and I made those 8×12's move some air..
Yes indeed! Just ask Duane Allman, Malcolm Young, and Adam Jones all of which used the 1986 bass version Plexi along with many others. Well you can't really ask Duane or Mal anymore I suppose, but you can still hear them!. It's also very easy to convert these to the super lead circuit but I would be inclined to leave it in it's original form and maybe throw a treble boost in front. Either circuit bass or lead is killer tho!
I have a 71 Marshall bass model and it sounds great!And a 72 100 watt super bass which has a blown transformer.What kind of transformer would be good to use to get the same power and sound?Thank you.
That's a great tip running that wire to the standby switch.
And those testers are the shit.
Great content as usual man !
I have a 1973 model 1986 bass amp and I really like it. It's a amp that I'm not getting rid of!
Those 1986 models sound sweet
One of my dream amps!!!

I've never seen that tube tester and matcher. Those seem really nice!👍
The big gold foil capacitors are made in germany by WiMA, also used in Vox amps.
Thank You
Ive got a chance to get a 1975 superlead for 1600 bucks right now. I imagine it will need some servicing, your videos will be very helpful..
It was tested on 4th of December 1970 we don't use US date conventions in the UK we use ours perhaps you should check these things mate
That's good to know and very important. Ese
I picked up a MINT 1969 year 1986 Bass head 50 watt dead not working getting it reworked all transformers tested and rewound if need be One Bad Larry
You're going to release the "Magic Smoke" !!!!
????
Pretty different from the cell phone parts amps of today
I’m not sure what you mean
I've got a 69' metal panel 1987, it's the organ model
What about it?
Not much 😂 looks identical
@@dalepiwek I’m sure it sounds good
I've actually changed it quite a bit. Now it's a 4 stage plate driven and it's killer
@@dalepiwek Lets hear it

Heybeor
Which is it. PT or OT?
It would be helpful to cut to a view of the schematic when discussing the mods you are about to make.
Got it, I have the schematics in my head, but I will next time
