I am contemplating building an Ultimate 70 primarily as a learning experience but I do not have a Dynaco St-70. I looked on Ebay and saw several with most of them being more than I wanted to spend. Since I am replacing almost everything do I need to be concerned if the old one works. I understand that the Ultimate uses the Dynaco transformer so I guess I need to be sure the transformer works

Any suggestions or gotchas?
any ideas on where to get a cheap ST-70
Can I get a chassis and then buy a transformer?

Also I am a beginner is this kit a good starting place?

Frank is the guy but in the meantime here is a link to a place here in Chicago my brother and I have both dealt with. My brother did everything on line, I actually went to the location and saw real people.

    I am not entirely sure what ST-70 parts you need for the kit, but, once you do find out you can get anything and everything here:

    I haven't bought anything from them but when I was looking at throwing together a Ultimate 70 for a gift I was planning on buying the parts I needed from the ST70, then finishing it with the U70 kit.

   I haven't built a U70 but a regular ST70 is certainly not difficult to put together if you are patient and are willing to take a bit of time to learn how to solder cleanly. You want to be careful as there are, naturally, some high voltages floating around in there.

Thanks for the replies.

I have checked both the dynaparts and the  web pages in the previous post and it looks like Chassis and transformers can be found. However I noticed on both pages that the chassis was currently unavailable - they must be popular. I saw some ST-70 on E-bay and I think there was 1 chassis

The choke would be easy to overlook. And the bias pots.
