They have 3 wires and when they're connected, they replace the smaller size speakers in the console, the woofers still work in the console. They help improve the mid and high range stereo effect. There are also connectors for a regular 4 speaker setup.

That's an extension speaker for the RCA console.

These consoles were made in Canada and quite different from the US consoles. We did have a few US-made color TV sets and combos before RCA started to make their own color TV sets here in the late 1960s (I don't know exactly when). Here are some pictures from one of my Canadian TV sets, this one is f...

I manage to do simple fixes, I'm okay to replace minor stuff or bad capacitors. I did fix a few old microwave control panels and my 1980 GE electronic toaster oven that got a bad transistor but not too good at finding what's wrong with audio systems. One of my RCA Victor solid state console has a de...

1967 was the last year for the variable pitch transmission. Both the 300 and 400 transmissions lost that feature on the 1968 models. I owned both a 1968 LeSabre with the two speed ST-300 and a 1968 Wildcat (an early production model made in 1967) with the ST-400 transmission, I have the shop manual ...

Here's a larger view of it.

Lots of cool stuff!! When I got to the photos of the Honeywell relays, I grinned. My boiler stopped heating last winter, during a cold snap, of course. At first I was a afraid it was the circulating pump, but then I noticed some corrosion on a gate valve directly above the relay and yes, then I saw...

That's a really nice car! I've only drove one 1963 Buick and it was a LeSabre 4 door hardtop with the low compression 2 barrel 401. I much prefer the Electra from that year to the B bodies, the rear quarters and taillights are much nicer. I really like the looks of the 1974 Electra, unfortunately, 1...

I have to say I'm not too good at fixing electronic stuff! And while I did minor fixes on my 75 Buick's Automatic Climate Control, I gave up on the idea of trying to fix it on a 1967 Buick that had it (I parted out that car and the only a/c part from that car that went in mine was the evaporator!). ...

I subscribed after a friend told me about this site. I have a few consoles, nothing fancy. A few Canadian RCA Victor solid state and hybrid consoles, a Zenith console/TV combo, two small German Saba tube consoles and a few more receivers and radios and old color TV sets. Most of the stuff I have was...
