Somewhat less photogenic than the Aric, the Von Gaylord LAD-L2 is also a two-chassis minimalist preamp. There’s much to be said for a pair of 6SN7 tubes (currently some lovely Raytheon VT-231s. Thanks, Michael!) backed up by a 25-pound power supply.
Not very creative, but my OCD today had me color code the labels on my products from most gentle to strongest so I can easily word up the scale to stronger products during my restorations.
Yeah it took a while to work it out based on experience.
I used to have it color coded by type and then ratio within that type.
For instance all the APC's were one, all the Rinseless wash's were enough, misc were another.
Then I learned that it was better to group them based on overall power vs type.
For instance a 30:1 of Blitz (a rinseless) is the same basic strength as APS at 15:1. They use different chemistry to clean. Since no two pieces of gear are dirty the same way there is no magic 'best one'.
A picture of my Weston 978 FAA tester I just made all pretty. And I tested it against my reference standard Western Electric 15750-L2 and the Weston is spot on accurate.
The 978 was built for the Civil Aeronautics Administration, predecessor to today’s FAA.
It used a 5 kHz signal for its mutual-conductance test, rather than relying on the power-line-frequency approach associated with many classic Hickok testers. This was done claiming it would yield more accurate results.
Classic Hickok testers derive the test conditions from the AC line-frequency system rather than using the Weston’s dedicated higher-frequency approach.
Pretty cool technology for something approaching 80 years old.
