NAD Marshall Vertical Input JCM800 4010

[jcm800gridlock]

A 1984 Vertical Input 50 watt 1x12 JCM800 4010 Combo.

It appears to be all original with a dreaded G12M70 speaker inside. The amp will be going to my tech tomorrow for a checkup. I’m assuming that it will need new tubes and filter caps.

The amp is in a decent 9 out of 10 condition .

As for the G12M70, I have a Celestion Creamback and a C90 boxed and stored away to try with the amp. If those don’t work, I’ll look for a late ‘70s G12-65 or a Scumback to swap in.

Store phone photo for now.

FYI, I actually joined this forum after another Marshall forum shut down and my form name came from my first JCM800. That amp was an ‘83 4104 (same 50 watt circuit but with 2x12’s. There were no bad tones from that amp at band volumes, so this new JCM800 instills some old sentimental value.

Beauty! Juicy find there. What a little beast of an amp!
Congrats on the score.

Congrats on the NAD, and a vertical input 4010 to boot! Mine loves the creamback I have in it, give it a go. I've no experience with the G12-70 speaker but the creamback was IMHO a big improvement over the stock G12-65 that came in it.

You're such a "gear whore!" And I mean that as the sincerest compliment!


HNAD, Again!

One of Marshalls greatest combos!

Supercongrats

Mine is an '80 model, an old barroom soldier I think. A little beat--up and a large stain running down one side, won't come out....but it still roars

HNAD!!!

What a score! One of the best amps I've ever heard was an early 80s vertical input 2204 I used to own... One of my biggest life regrets!

Let us know what speaker you decide on in your new baby, I don't know what Marshall was thinking using G12M70s. I recently bought a 1x12 cab that had one inside and I experimented with it... It's ok for clean but soon as some gain and distortion is involved it falls on it's face.

My tech recommended putting a 16 ohm speaker in it, he said Marshall’s sound best with a 16 ohm speaker. I believe both my C90 and my Creamback are 8 ohms. He recommended a Gold since I like my amps with plenty of bass.

I’ll definitely try the Creamback first.

By the way my tech called me after retubing it, he told me to never sell this amp, and if I do, call him first. Guess that it sounds pretty good with all new tubes. He had to order filter caps, so I’ll pick it up next weekend.

Any 4010 for sale in my part of the world has been priced to high or in tough shape. I have been looking on and off for 10 years. Years ago I found a 4104 for short money but really was after a 4010.

 

[DragonCrestPC]

Congrats! Vertical input 800s are some of the finest amps ever!

Great amp. Nice score

Don't listen to your tech and find an original 8 ohm G12-65


I had one of these amps.They sound great with the original G12-65

I had a medical issue come up and I had to sell it. One of my biggest regrets was letting that amp go.

I had G12-65’s in my early ‘80s JCM800 4104 and they were made for that amp. I’ll definitely be on the lookout for a deal on a vintage G12-65.

Congrats! Best combo amp ever! I stupidly sold the one I had years ago and have always regretted it. Now they are going for lots of money. Mine had the G12-65 and I think 16 ohms (actually says 15 ohm on the speaker) is the stock ohmage.

This think it is 8 ohms.
