    EICO 460 scope

    Your brightness shift across the trace could be due to a non-linear sweep. (the ramp part of the sawtooth H. sweep waveform could be curved rather than perfectlt straight.) Brighter where the sweep is slower and dimmer where the sweep is faster. Have you tried putting a sine wave from an...

    EICO 460 scope

    I have a 460 that I built from a kit when I was in high school back in the '70s, and has the same glitches in the circle trace you get with the Hor. selector on 60 Hz, and Vert in Cal. These scopes are TV repair shop scopes and not lab-grade like Tek or HP. It uses an unregulated power supply...

    Opinion-Advice Winegard YA-1713

    The YA-1713 is a 10-element yagi for VHF-High band (Channels 7 - 13). They are great antennas if you have any DTV channels broadcasting on VHF in your area. Only a handful of DTV stations are using the VHF-Low band (Channels 2 - 6) so lack of low-band should not be an issue in most locations...

    Sony TC-K890ES... WOW!!!

    I bought one of these new in about 1993 and I agree it's an awesome deck. High-end cassette decks were disappearing from the marketplace at that time, and I wanted to buy my "last" deck before the good ones were gone. Few maufacturers were making 3-head single well decks by that time. I...

    Newcomb AM/FM tube Radio

    Don't have any info on that radio in particular, but 60's vintage sounds about right. Newcomb made school/classroom phonographs, so this radio is a similar type of ruggedized unit intended for classroom use. My Jr. High school had a bunch of tube type Newcomb phonos, with 6 x 9" dual-cone...

    Help to identify this Fisher!

    Are you sure there isn't a "5" in front of that "61"? Sears sold a full line of components in the mid-late 70's made for them by Fisher. Hence the "Sears Audio by Fisher" brand. Sort of like the MCS gear sold by JC Penny. The 1st 3 digits (in front of the decimal point) in a Sears...
