I built it with el84 tubes wired ultralinear and 5ar4 rectifier. The power transformer is an Edcor XPWR008. What would be a good fuse amp rating for testing? If testing goes ok what value fuse would be good for long term use?
To me this amp was a more difficult build than the two sse's I have built because of all the connections, more output tubes and transformer wires, so I am trying to proceed with caution.
I did not put the feedback caps in place yet as I am not sure what they do or if they are needed.
The output transformers are Edcor CXPP25-MS-8K/23% which have 4/8/16 ohm taps. I attached the feedback to the 8 ohm tap.
Any tips or comments would be appreciated.
I put it in a pessant 3u chassis from diyaudiostore. Here is a photo:

See my SPP build series in the link below. Start with attachment 2. If the pictures look funny it's because I put some components, including the terminal strips, on the bottom of the chassis.
