In this video we’ll diagnose and repair an amp which many thought had legendary rock and roll connections. This is an Orpheum labeled Valco amplifier, but as we will discover, it is truly a Supro Model 24 (S6424) underneath, an amp that for many years was assumed to be the amp that Jimmy Page used on the first Led Zeppelin album. We now know definitively that this is not the true Zep amp, so we will examine the evidence. Also, we will talk about replacement tubes for the fabled 6973 which power this amp. The 6cz5 is considered by many to be the best drop-in replacement, but is it truly a drop in substitution, or are modifications necessary? We will also talk a bit about the importance of having the appropriate speaker for your vintage amp. This one originally came with a Jensen C12Q, but that has been replaced with a Realistic speaker made by Utah. We’ll discuss why this speaker isn’t ideal for this amp. At the end of the video, we’ll demo the amp with a PRS CE24 and my Zio Meteorologist.
