Is my Dynaco Stereo 400 worth repairing for resale?


After all the years, I’m sure it needs a good cleaning and at least all the cans replaced.

Will I even break even?

I’m sad to say James Bongiorno is no longer with us. I never realized how many of the products he designed, I bought over the years.

@buellrider97 : I have an original owner pair of 60 watt mono SS amps from South West Technical Products. Designed by James Bongiorno - full complimentary symmetrical circuit using the then-new PNP output transistors. Before that SS amps were limited to using only NPN output stages. JB went on to design the high-power Tigersaurus amp for SWTP which became the Ampzilla kit. 

@curiousjim : Little known fact is that James Bongiorno joined Rectilinear to work on the model X  speaker. Later he joined Spread Spectrum Technologies.

Interesting you mention the Rectalinear X. I tried to find a pair unsuccessfully in the late 1960s. I found it a fascinating speaker, sort of an augmented full range speaker with a whizzer cone mid range used from 100 Hz to 8kHz, a 10 " acoustic suspension woofer and a simple 2" cone tweeter. Add it used a series crossover  and it was a pretty unique design(even today).
