Cleaning Marshall guitar amp potentiometers

[@freakcomposer]

I can’t believe that I found this video! And I can’t also believe that still useful and good people exist on the Internet! Thank you so much brother! Your video saved my two amplifiers.

[@pahkina1167]

Nice! 👍

[@derekcoffey4525]

Absolutely brilliant video, to the point.... I bought a second hand amp a few days ago which was very crackly and this video allowed me to fix it and I'm delighted now... my first time fixing a problem on an amp as well, I'm very proud of myself! 😂... thanks so much

[@pahkina1167]

Glad to help Derek! Greetings from Finland! 👋

[@tobiasrechsteiner8459]

absolutely love that you played Mark knopflers fill-in lick from "calling elvis". love it big time, cheers!

[@BritInvasion1981]

Thanks, this helped me get mine up and running again.Love the bit 'Calling Elvis' at the end there too :D

[@scutchingss]

Awesome, just got my old amp and guitar out for my daughter and it's crackling. Typed in on here and it's the exact same amp haha. I shall be doing this over the weekend for her. Nice video mate!

[@maxgrim1672]

I had to replace a regulator last week. I got new original controllers online...and I'm really happy that I was able to save the Marshall :-)

[@GSGSongs]

Thnx, worked like a charm 🎸🎶🎼

[@mrbartlomiej]

Thanks. It worked. Especially turning. A lot of turning!

[@pahkina1167]

Bartlomiej Piech Glad to hear! 👍

[@paulcowart3174]

What are the proper pots when replacing Thanks

[@JuxtaCrucem]

Lovely amp. I own a 5205 Reverb.

[@chrish3672]

I have an old Marshall Valvestate Bi-Chorus 200 Model 8280 2x12 Celestion G12T speakers ... it has alot of static noise with the pots and at times cuts out altogether Remedy?

[@TheeFeels382]

Nice tutorial. Simple and useful. Is it possible that this solution works for unresponsive knobs? I mean not completely unresponsive but my bass knob doesnt seem to work properly.

[@pahkina1167]

Go ahead and try. Don't think it will do any harm. Glad you liked the video!

[@Random245]

Going to try this on my Lead 12, getting lots of noise when turning the dials at the moment. Edit: my speaker cable was so short I've had to disconnect it to remove the box, will have to solder back on after.

[@bozakarlin9034]

On my ROLAND JC 50 the potentiometers are cleaned with WD 40, which has oil in it. The amplifier has been working great for 10 years.

[@pahkina1167]

I don't recommend oil.

[@wolfpack78811]

Do you have to de charge the capacitors before touching in there? Never tried this before

[@pahkina1167]

Don’t know, I just unplugged the amp from 240V and waited some time before opening the cover.

[@roundtheloopandback]

OK, people listen carefully, do not touch capacitors that are charged, some of them hold enough charge to kill you.

[@Blackdog4818]

Is there any danger in spraying on the board? Or plugging it back in while it's still wet? Did you wipe it off?

[@pahkina1167]

This spray vaporizes quickly, no need to wipe.

[@Blackdog4818]

I have the same amp, but there doesn't appear to be holes in the pentiometer. Will the oil (liquid grease?) get in through to the inside?

[@pahkina1167]

Blackdog4818 Yes there’s actually not much oil I think, it just freezes the dirt. Spray from different angles and many times, hope it works.

[@roundtheloopandback]

Some contact cleaners are flamable until dry, wait until everything is bone dry (deoxit d5 is definitely flammable while you wait and takes 5 to 10 mins to dry)

[@andreas5153]

Thanks! Did you buy it in Norway?

[@pahkina1167]

No I live in Finland. Bought it 30 years ago here.

[@andreas5153]

@@pahkina1167 I see. But the sign on the back is in norwegian. There is also a marking on the "N".

[@pahkina1167]

@@andreas5153 That's possible. Bought it from a music shop and it was a preowned then.

[@andreas5153]

@@pahkina1167 Great amp though! I run the head version through a 1969 4x12 with greenbacks. A fantastic combination.

[@maxgrim1672]

Why are you pulling off the buttons and spraying them on from the front? The controls have a hole on the inside! You spray the spray in there. That's easier. I have 8 Marshall Lead 12(reverb) I've done it so many times.. That's what the holes in the controls are for.

[@milliardalaras3351]

Hello what cleaner should i use? Can i use ed 40?

[@pahkina1167]

Milliard Alaras Use the same as I did, see the video.

[@roundtheloopandback]

Deoxit D5 (search amazon as the link Is excluded from direct linking)

[@Tooweemusic]

Thanks for this video, it helped a lot :-) Who's that lick you play at the end from ? I've heard it so many times, but can't remember who plays it :D

[@pahkina1167]

Glad to hear! The lick is from Calling Elvis by Mark Knopfler. It’s a Dire Straits song.

[@Tooweemusic]

Pähkinä yeah that’s it ! Cool lick ;)

[@Byrondt]

you ve sprayed the whole board. didnt that caused any problems

[@pahkina1167]

No it didn't

[@andyholdstock4559]

Cool and no bad comments so must be cool have an old valvestate.could be interesting.thanks

[@tomasotreasaigh111]

Will WD40 work?

[@pahkina1167]

Not really

[@raymondjiii]

Nice. I'm going to try to something similar on Marshall Valvestate. First time I've ever seen someone NOT use De-ox-it spray. I've been using it and I think it's okay. Curious about the brand shown here. Thanks for the great video!

[@matthewmcdonald4222]

Deoxit does not have oil in it either

[@raymondjiii]

@@matthewmcdonald4222 there are three versions of Deoxit: D5, DN5, and D100. D100 has no solvents but D5 is highly flammable, feels like oil, contains aliphatic hydrocarbon. Given the residue it leaves behind - I think it has some oil based substance. It does work though so I’ll keep using it until I find something better.

[@matthewmcdonald4222]

Deoxit D5 does not have oil in it and as for being flamable who cares because I'm not putting a lighter up to it and it dries in seconds

[@raymondjiii]

@@matthewmcdonald4222 I disagree. I can wipe the residue off with my fingers, a cloth, days after.

[@matthewmcdonald4222]

@@raymondjiii then you must be over spraying I don't know what to tell you nobody else has said that

[@darthjump]

Maybe do it upside down so your spray doesn´t flow over the main circuitboard.
