High-plate Skyline build

Looks great Ian, a proper brother amp! How similar is the sound/feel between them?

Thanks Dan. They are surprisingly similar considering the Dumble has NOS glass and the new one has current EH EL-34s and Psvane 12ax7s. It has that low end fullness you get from a 100W vs a 50W and the vol pots react slightly differently (I chose 2-35 over 10% in the Dumble)

Looks great imo, killer job

Amazing work Ian. A reference build.

Might be a nice sticky, right? Reference builds.

Dude!! You rock! That is some art!!

Is there a known, or estimated, serial number range for the amps with bolt-up chassis?

#183 is a five-piece chassis.

[Edit]

I think you are asking the wrong questions. It's one thing to ask for archival purposes, how many, known or estimated, there are, and another to ask: "why is this significant?" My own thoughts are that this could be because there were no specific dimensioned chassis available at the time and MrD needed something of very specific dimensions (perhaps for a cab he was working with), but then... why did he repeat it, with #183 for example?

What are your thoughts?

That's a bit of work... if it were sitting around my shop, it would eventually get used. Maybe this... ?

The earliest I have seen is #0128 and the latest I have seen is #0195.

I think there were perhaps a few reasons:

- Durability - these chassis are STRONG
- Keep the entire process under his control
- Cost - once set up they are really inexpensive compared to a large run from a metal shop
- Serviceability - the modular design allows you access that other chassis do not. I have already done work by removing the side and front panels - super easy

Regarding the size, I think he still stuck to a standard size (although the one I worked on was slightly smaller in length). From what I can tell and from others that have been inside other amps, the dimensions are pretty consistent.

That looks just like the amp Randy California had.



Also, what gauge aluminum is the bottom plate?
