Any love for the old JCM2000 DSL 401 combo?

Looking for something I don't remember what.
Still use mine on a regular basis. It's a 2009 model, so all the overheating issues seem to have been resolved. As JohnH said the speaker isn't up to much and I replaced mine with a 1980 G12-65. The singer / rhythm guitar in my jam band plays through mine all the time and loves it.

I had a '99 DSL401. The board needed the solder joints redone after about 6 months. I fixed it 6-7 times while I had it.
A great deal on a DSL40C came up & the DSL401 went. I don't miss the 401 at all.

Had one for a while.Bias current flowed through MV pot.
Oof!
The two DSL40Cs I have are far superior although I liked the clean channel on mine

Lots of heat bridge rectifier solder issues with mine

My tech stopped speaking to me over that amp lol!

Never had any issue with mine and I giged them hard then... so maybe yours was a "Monday production"....

A 401 was my main amp for about 12 years.
I had a 2005 401 I bought from new that gave me no issues whilst I had it.
The faceplate did get quite hot, but no mods were needed.
I even had it stacked on a 1912 cab to enrich the sound and projection.
On the downside though, I used it almost exclusively on the Clean channel, getting all my gain from an up-front Boss GT-10.
I like lots of thrashy gain and the 401 just couldn't deliver on that front (IMHO).
It was just too raspy for me.

As I started to lean more about valve amps and the 4CM setup (mostly from the MF'ers) I found other weaknesses that finally killed off my love of the 401.
Chief among them was the parallel loop, and my first attempts at 4CM using the GT-10 were a frustrating failure.
The use of OD's out front was great, but TBE's just seemed to drown in the loop no matter how it was set.
I tried using 'dry-kill' on the TBE module setups, but you can't really stack TBE's with 'dry-kill' on each one.

In the end I gave up and traded it on for a DSL40CR and treated it to a GT-100 and Zilla 112 cab upgrade.
Now that combination, using 4CM and MIDI, is fantastic.
Series loops all the way for 4CM setups.

Strangely, I did become a fan of the stock 401 speaker though.
My 401 came with a 16 ohm G12T-100, and I had to swap the 8 ohm G12B-150 out of the 1912 cab to be able to load it correctly.
I went (rather un-imaginatively) for another 16 ohm G12T-100 (for a parallel 8 ohm load) and thought no more of it.
After I sold the 401 I snagged a Valvestate VS65R and decided to run it with the 1912 rigged in parallel.
To do that, I had to swap out the stock 8 ohm Goldback SPK65, and went for yet another 16 ohm G12T-100, to bring the load back to 8 ohms.
The dual G12T-100, open & closed combination is killer for an SS hybrid amp.

So I leaned a lot about valve amps from the 401, and am respectful for that.
It also brought me to the MF :h5:

But in the end it just wasn't the amp for me.

That was 1 of the issues I had with mine. The MV pot failed & red plated 2 of the tubes.

I'd always prefer a 2x EL34 over 4x EL84 when talking about Marshall amps.
So I personally would also chose a DSL40C (or CR) over the DSL401
