This makes me glad to have sold my Mesa. These days, I'm playing Mojotone 5E3 and 6G3 Deluxes. They sound good! The construction is like what Leo did in Fullerton. Mojotone went to some lengths to re-create those amps. I like the cloth covered push back wire. There's some extra satisfaction in playing a Warmoth guitar you built through an amp you built and gigging with them.
Thank You for another great Mark IV vid .....so i got one Mark IV B ....and just recently had a issue the Main Output Level / Recording volume pot is doing nothing also the Lead Drive pot isnt aparently effecting much .... any corelation between these two pots effecting one another or just my bad luck and need to replace these two ? ......any source you could recommend for replacements?
Those AC plugs are an IDC design, for Insulation Displacement Connector. A variation on old-style telephone and data connectors where the *solid core* wire is pressed into a forked tab which slices through the insulation. Not a great design for 120 volts however, especially with stranded wire and a fan motor that might have an inductive surge at turn in. Okay for replacing a plug on a table lamp, I suppose, especially if the lamp uses an LED bulb, but a 100 watt incandescent bulb might pull enough current to overheat the plug, especially the original cheesy right- angle plug that you replaced.....BTW, I bet I have some of those square courtesy outlets!
Hi, I own a Mesa Boogie Mark IV combo amp, can I run it without the fan turning on? Just for playing at home at low volumes, I don't like the sound of the fan continuosly on. Thanks
That was a fiddly little repair with that fan plug..! For such a big named amplifier, you would think some form of different connection would have been easier with the design.! Nice one though Lyle..Ed..uk..😀
Have you heard of many amp techs simply refusing to work on Mesas any more due to the various hassles involved in servicing them? Bias issues, confused layout, and obsolete parts aside, it seems doing even basic maintenance on them involves disassembling half the amp to get to trouble spot. Regardless of tracking down replacement parts, just factoring in the hourly bench rate alone must make them some of the priciest amps to need work.
Oh, and it’s not just Mesa’s. The Peavey Classic and Fender Bassbreaker are a few more that are stupid impossible to fix under the value of the amplifier.
Crappy lamp cord cap time. You have to split the zip cord back about 1/2 inch, and you do not strip the wire on those. Those spikes dig into the insulation, and yes, it's hokey as _____! The ribbed side of the zip cord is supposed to be the neutral.
Ex- IECA, IBEW, IEEE, NEMA, and a few others. I quit paying my dues. It's like the neon sucker sign on my forehead. After I missed 4 payments they repossessed it.
@@0megalul309 I have owned and repaired more Mesa amps than you most likely have. And yes, I can afford there amps. I am not going to start a pissing contest over your comment, but your comment is simply argumentative and not true.
@@fiddlix I just pay to send them to mesa to fix. No need sending them to incompetent techs who probably make comments like throwing them in the garbage due to their inability to fix them. 🤷 There's a reason why people still buy and maintain these amps after 30/40 years but just cos of subpar techs they get a bad rap lol. You don't send your sports car to the local hippie to service it and the same thing applies to most modern multichannel amps that cost north of 2000 USD.
Statement from The Indignant Englishman "Mesa??? No, Sah! Never, Sah! Not on your life, Sah! My card, Sah... Good Day to you, Sah!" Mesa looks like A Hunka, Hunka Burnin Junk. I never liked their amps, but all of the Mesa repair videos I've seen on RU-vid confirm that they are poorly designed, overpriced and hard to repair.
