be back in 2 and 2

Everybody remembers this:

I lashed up my Sony muter plus delay for last nights Packer game:

Jayden and Jordan after the game

old Sony TV remote, Sony stereo remote, muter, 9 volt power supply

The delay itself was supposed to be 2 minutes but it came out as 2 minutes and 2 seconds.  It actually worked pretty well even for football which is a little less time regimented than modern baseball - George Carlin must be spinning in his grave !

The muter was connected on one leg of the left speaker.  The right speaker was disconnected.  One question: does it harm an audio amp to be run without a load ?  Certainly that is true with an RF amp but an RF transmitter is generally run at high power.  Most casual listening to an audio amp is done at milliwatts.  So the output stage should be able to dissipate the power.  But it's prudent to run the amplifier with some kind of higher impedance load in parallel all the time, maybe 50 ohms ?

Another approach would be the custom Sony remote - that would eliminate the need for the muter and just use the Sony stereo as is.  I can save the muter for the MR-1010 when I listen to the Brewers on AM (usually only Fridays during football season in Door County).
