If anyone has a output transformer for the 100s/200s/Sorado/... they are willing to sell, please let me know.

Thanks!

Have you considered the Triode clone tranny?

The Triode power transformers are superior to the originals as it is rated for more current. The original Sunn power transformers from Dynaco were not rated high enough and sometimes failed in time. The Schumacher power transformers were a bit better in that respect.

The original Sunn output transformers, especially the Dynaco ones, were excellent, and many people grabbed Sunns when they were really cheap and used the output transformers for their hi-fi projects, so finding original Sunn output transformers is a long shot. The Triode transformers are excellent quality.

I agree with EdBass and Soundmasterg .....the Triode clones are the way to go. I've used both their power and output transformers on Sunn restorations with excellent results. Direct drop-in fit and identical wire color code. Not only higher ratings, but they are new rather than 50 years old!

Good luck!

I noticed the choke is also available from triode.  I've not seen a direct replacement for the 3-RT reverb transformer on their site.  I want to use these trannies in a 7-knob chassis like the Spectre so an equivalent for the 3-RT is needed.  Those I noticed at triode had higher in/out values than those I found on the 71 spectre schematic. I did see one at Mercury Magnetics listed as the reverb tranny for a Solarus. If I'm not mistaken, that would be the same reverb tranny used by the Spectre (3-RT)?  Is that the case?
