My hair is as long as Ricky's and I am past 50 or so. :)

50 or so what? (FWIW I'm past 60 with about 1/2 that hair length, but solid chrome)

Obligatory Marshall content: I'm following this thread with interest, thanks for the work Ricky. I jumped in and went the distance getting the 2555X head for under $1K, then followed up with the cabs making a full stack. Total overkill, but totally satisfied.

Yeah Mickey, I need to dig out my '83 2204 and that '82 4010 that runs at the 400V B+ and get them in the mix of clips.

Did you see where I added the clip of my second Jubilee which is the 2555 Clone? I had forgot that it had a few minor tweaks which I listed in one of the permalinks later on.

Was wondering if you liked the clip of the 2555 Clone and could hear a tonal difference with it vs the '87 Silver 2555?

Bummer as the variations I hear in person playing the amps just do not come through in the clips. Subtle things like EQ character, gain/distortion voicing and even slight changes in sizzle and note decay fizz do not show up in the clips.
I do hear differences but I have to first state that the clone was louder, not to the point of any distortion or saturation. That in itself usually provides more presence, punch and definition. I think it is heard when listening and comparing the two. Of coarse the capacitors and transformers are helping to make those differences.

I just have to wonder if the clone was turned down to match better if they would sound more alike.

They both sounded good.

I am more than 50 years of age.
My hair looks similar to this with the skunk stripe only longer, past my tittes.

Yeah, I would say you resemble a singer in a band that is on the tip of my brain. Not coming to me now.

:D

Regarding the Jubilee amps and volume level in the clips, the amp clips I made were closely matched in volume/output level using a very sensitive dB meter I have. I left the dB meter on a small stand just out of view from the video. I first ran the TSL100 with all its settings from a previous nights gig. Then matched the volume on all the following amp clips to that same dB level.

The '87 2555 Silver Jubilee had its MV around 6 while the 2555 Clone was around 3 on the MV (those are aprox as I mentioned all settings in the clips, would have to go back and listen to what I said to double check). But the Clone has a .68uF cathode bypass cap on V2A. So you are hearing the enhanced frequencies from that added cap. Might go back and remove that .68uF on V2A on the Clone or put it on a switch later on.

Any capacitor in the cathode circuit will not only enhance frequency but add volume as well, volume more so and frequency not so much at V2A. To be fair both should have the same circuits and values.

On my end the clone was definitely louder no matter what a decibel meter may have indicated in the room. To me that makes a great deal of difference in what one hears. Cleaner additional volume enhances everything.

Great job! Thanks for sharing! I liked different things about all of them. I've been thinking about doing something similar. I did a JVM 410 vs 410HJS video a couple years ago. Maybe it's time lol
