Title: Solarus - model changes
Post by: Solarusizer on October 10, 2023, 01:40:44 pm

Hey Everyone -

I just got a good deal on a backup for my treasured Solarus.. and found some surprises. Firstly there is no mid-boost switch, which is kind of a bummer. But what I was surprised by is that it only has 16 & 8 ohm outs. My other Solarus has 8 & 4ohm outs, which is great because  I run it with a Sceptre 4ohm cab.

I'm hoping someone here might know the details of which design was first, and when those changes were made. Thanks!

Open up the Catalog thread and use the text search function (control f) to search for Solarus. Might not work on a Mac but OK on Windows and Chrome Book. There is a thread here that discusses how to change the output impedance between 4/8 and 8/16. You need to be handy with a soldering iron to move some wires around.

The first models did not have the mid boost switch. That was added later. A useful function, IMO. Too bad it wasn't foot switchable.

All of the models have the same transformer, and those have 4, 8 and 16 ohm taps. As loudthud said, it's not difficult to switch between them.
