Soldano / Rosamp SLO50 / 50W Amp Build

[RoadShow]

There have been a lot of posts regarding Rob Robinette’s Soldano analysis, schematics, and building different versions.  The information is just fantastic.  I also bought the Kuehnel Soldano SLO book and digested that.  2 years ago I began heading towards a Soldano clone build.

I was leaning towards a turret board  and began layout of a RR 6L6 version and at the same time was considering buying the Rosamp kit, for a couple of reasons:
1)   Nice chassis that was ready to go, spittin’ image and function of the Soldano
2)   Circuit board and components ready to go
3)   Assembly required

I decided to go for the Rosamp, I bought it last summer, I didn’t actually start building it until early this year, and so often it wound up on the back burner.  I finally buttoned it up a month ago, and it sounds fantastic!!  Quiet as can be!!  I did change the crunch resistor divider network, it was too over the top for me.  Last week I built the head cabinet.

I just want folks looking for this type of a build to know that the Rosamp is an excellent way to go.  Last summer when I bought it, it was $758 shipped to the USA for the complete kit less tubes.  Today, it looks like it's gone up to $888, inflation and tariffs I guess...

It was a great way to go.

Hello, I’m also a big fan of Mike Soldano. I modded a Jet City 100HDM that I bought second-hand for $300, including a 4x12 cab with amazing Eminence speakers — way more aggressive than V30s and worth around $500 — into a full SLO-100.

Before finally getting it to work, I went through all kinds of trouble: leaky tubes, exploding capacitors, and a failed optocoupler.

I ended up replacing almost every component to get it working… and now, it’s got problems again, haha.


And I have a new project — I’m going to make a small preamp box based on the SLO-100, with both a 3-tube version and a 4-tube version, which I got from DIY Fever.

Yes I do have an account.

I have the same problem with the tubetown forum.  I recently tried to register for 2 months several times and gave up.  Yes, I checked my spam folder.  Never got approval or heard back.
