Hi,

> And while we're on the subject does anyone know why HZ changed the pins on the clones to not fit 122's etc?

If you're asking, "Why doesn't Hammond-Suzuki" use the 6-pin standard," it has to do with UL listing. The 6-pin standard was developed in the '40s or '50s. Hammond changed to the 11-pin standard in the early '80s, for safety reasons.

UL doesn't allow "high" voltages ( > 42V) and audio to run inside the same cable. It's not as big a deal for the 122, where there is a 50-80VDC level being added to the audio. The biggest issue is in the 145/147 6-pin setup, where there is 120VAC running in the cable alongside the audio. In fact, the halfmoon switch on a vintage setup as 120VAC running inside its case.

Why H-Z used the 8-pin connector on the newer products is anyone's guess ...

Regards,

-BW
