Thanks all. That clears up some of the mystery. Al, your advice on how to power-up the unit will be especially helpful. I have no intention of selling the units, but was more interested in it just to know the value and rarity of the components. Albert P, thanks for the links to the product brochure. If I locate more information I'll post to this thread! Cheers, Ear |
Looks like you can download brochures for the amp and preamp (but not the integrated amp) by registering at The Audio Circuit. It all appears to be from the mid-to-late 1950's, based in part on the inclusion of "RIAA" in the phono equalization selections. These pieces are undoubtedly quite rare, at least outside of England where they were manufactured. Tannoy is known mainly for their speakers and speaker drivers. Many of their vintage speakers and drivers are quite valuable, including some from that period. In your other recent thread you were asking about value. It's anyone's guess as to what they would sell for. My guess would be a few hundred dollars for each piece, or perhaps somewhat more for the power amps (I see in your other recent thread that you have two of them; a pair will be worth significantly more than twice the value of a single, since it can be used for stereo). BTW, if you are tempted to try them out using a 120V to 240V step-up transformer, as you may realize the first time that is done the voltage should be brought up very slowly (over a period of many hours), using a variac or other variable ac power supply. During that process check that the power transformer isn't overheating. And before doing any of that, all of the electrolytic capacitors should probably be replaced. Finally, as with any tube power amp or integrated amp that has an output transformer, the power amp and integrated amp should not be operated without a speaker or equivalent load connected.
