Title: Need Output xfmr feet for 200S
Post by: Greg_M on November 10, 2010, 07:44:06 am

The 200S amp that I bought has the feet broken off the output transformer. On this model transformer, which says "Dynaco" on it, the feet were "L" brackets that went up underneath the bell covers. Some have the feet built into the bell covers I hear.
If you have a blown output transformer for a Dynaco Mk III or 200S I could use those parts.
I can make some feet, but it's not as desirable as not having to make them, so I thought I would try here first

Thanks

Those L shaped feet were probably put there by Sunn to prevent the original feet on the Dynaco transformers from breaking. Most transformers that mount like that can't tolerate being hung upsidedown and bouncing around in the back of a semi. (Hint: Don't pack your Sunn upsidedown!) Traynor had the same problem but they got Hammond to weld reinforcements on the end bell. Just improvise something out of brass or steel.
