Info Needed: Interelectronics Coronation Four Hundred (400) and Consolette

Recommended Posts

Hello All, 

I recently acquired an Interelectronics Coronation Four Hundred (400) amp and Consolette preamp off of the local classifieds for a few hundred dollars and I was having trouble tracking down any information on the pair. A few google searches yielded one expired ebay listing and a few incomplete message board threads but nothing substantial. Is there anyone on here that has any information on the amp or could point me in the right direction. I was concerned with if was worth possibly cleaning up and putting to use or how much they might be worth in general. 

 

Thanks,

Jack

I have not met him, but I might have heard about him. This amp is currently in the possession of @sheltie dave who had talked about a few others in the area and their experiences with the amp. Hopefully, he can get it up and running proper. It seemed to work good for its age but had a reoccurring pop that would happen every 10 seconds or so. It was likely a bad cap or resistor.

Meet Willie !!! 

 

He is a VERY VERY COOL guy, and DIY designs and builds Triode amplifiers of all kinds, but usually VERY VERY GOOD ones. 

 

Ask around, he lives in Saint Louis, MO, and I'm in Warrensburg , MO, across the state from you.

Very nice Williamson circuit (or close to one). The output tansformer seems identical to that of the Radio Craftsman C-500 amplifier.

 

 I have bought 3 pairs of these with my best friend. but never had a chance to listen to them as he had suddenly passed away. He only finished restoring one pair and claimed the they easily rival his MC-30s. 

 

I already left the US and went back to Israel due to family reasons and the amps and rest of his gear were sold by his widow 😕..

 

Interelectronics was a small NY based company aimed to compete with Marantz. Rumor has it that later it changed its business direction to become Intel...
