Measuring Output Transformer Primary Z with the FNIRSI LC1020E LCR Meter


For years I had been measuring output transformer primary impedance using an arduous old-school procedure similar to Uncle Doug's and Skunkie Design Electronic's videos. Recently, this video from Mr. Carlson's Lab popped up in my YouTube feed - a significantly simpler process!

L > R: Peerless MT225, Altec 3000H and Realistic 40-1375

Although I prefer listening to my Altec 755As neat like a double shot of fine aged single malt, for certain well-recorded music, I hanker for richer harmonic overtones from the better spec'd Altec 755Cs.

Western Electric 131A/133A Inspired Amp - Mono

 

While I was relishing a pair of Altec 32C horns in the attic during the late aughts, unbeknownst to me, my stateside audio comrades, Dave V. and Joe Roberts, were praising the same horn's virtues in audio forums. When these veteran audio hobbyists consider the Western Electric 124 one of the finest-sounding amps they've ever heard, I listen. 

See Dave's (@Salectric) WE124 amp project and WECo 133A clone thread started by another 32 horn adherent (@gilmorneau) at Hifi Haven.
