1945 Navy Morale Radio & Shortwave and Radio Propaganda History
Marine radios are a personal passion of mine and in this video we look at a shipboard radio built during WW2 for the Navy. During the war, there was a massive race to create short wave radio stations and a radio infrastructure for propaganda. We’re going to talk about radio wave propagation, radio war propaganda, and also power up this old boat anchor and see what we can hear on the airwaves today.

Check out this 1962 Gibson stereo amp. This Gibson has independent pre and power amps. There is a stereo-mono switch that lets you run the amp in mono at 15W or stereo 30W, combining the power amps together right before the phase inverter. I go over the functionality and take a look at the schematic. Thanks for watching!
Laney Klipp 100 demo and repair discussion & the Sabbath sound
Переглядів 2,1 тис.7 місяців тому
Sometimes in amp repair even a working amp needs a lot to make it reliable and sound the way it should. This mid 70s Laney Klipp 100 basically worked, but there were a lot of issues to address. The plate voltage on these amps is incredibly high, about 600V. So with modern wall voltages, these tubes were getting eaten like a pizza. My bench can go over 120V so I biased the amp to 115V on a varia...

The Ampeg AC-12 is a rare amp, and rare amps make their way on to not-so-rare recordings. As music was changing in the early 70s, amp manufacturers were still holding onto the past. This AC-12 was made for accordion use while the sister amp, the GU-12, was being used by the Rolling Stones on Exile on Main Street.
