    Converting to a mono configuration - an old Magnavox drum console

    Thanks guys - yep these are just garden variety 8 ohm drivers I'm experimenting with sending the signal into both positive sides of each channel (tying the + together) in a parallel config - Initial tests are inconclusive... but it's fun to learn how to tie both channels into one mono channel...

    Converting to a mono configuration - an old Magnavox drum console

    I have been working on an interesting old 70s Magnavox drum console - dungeon chic model - The receiver is operationally in a very bad place right now so I'd like to replace the old receiver with a class D kit from parts express. Thinking about the layout of this console, I'm wondering if it...

    Magnavox with a companion speaker - summing circuit?

    OK - thank you -- I was referring to that 3rd resistor that goes down to ground -- here's a better representation of it -- in this sketch they are using a 20K ohm R -- because it's for an electric guitar -- When I tried this circuit I was not able to get any sound through with that R3...

    Magnavox with a companion speaker - summing circuit?

    Thanks Cademan - that is probably a better idea - sending signal to a small mono amp and then over to that external speaker -- I did try L and R straight to a test speaker ala Haffler circuit but it didn't sound very good - Would this work as a good summing circuit to use with the tape out (2...

    Back to the vintage low watt receivers. They are addictive!

    as a Pioneer guy, I ask myself... what is the cutoff between low and medium for the sx receivers? Did the sx650 silver face fall under the line for a low watt receiver? I'm working on a console pull from an early 70s magnavox right now - that 70s aestetic, low wpc output, backlit face... as...

    I'm confused -- can a function generator produce the same range of frequencies as a signal generator? For aligning AM and FM what frequency range of function gen would we be looking for?

    getting started with tuner alignment

    I've found this guy's videos helpful: I have a simple 2 channel Tektronic TDS 210 - So I just need a signal generator -- would I be better off going with an older used signal generator like an Eico 369 - the one used in the video above, or would it be better to go with something new like...
