Schreyer Audio SA7 Combo Amp #SA7CH2601  From Schreyer Audio

Originally Inspired by the 5F2A narrow panel Princeton of the late 50’s, the ‘SA7’ builds on a classic theme adding a few modern upgrades. Similar to the Tweed Harvard 6G10 version, we house the combo amp in the slightly larger cab and drive a 10 inch speaker for more volume output. The 5F2A/6G10 is an excellent ‘Class A’ circuit design and a studio favorite. The SA7 puts out about 7 watts when the output stage starts to compress. There is one volume, and one tone knob. The original circuit had two inputs and a ‘bright cap’ always engaged. We opted to go with one input, and a bright/normal switch for more tone control. The output transformer is upgraded to a Hammond 125CSE to give full body output. The speaker is an AlNiCo high end Weber 10A125 . The AlNiCo 10A125 provides an incredible organic, woody tone that complements the tweed circuit well. The original 5Y3 rectifier tube is substituted with a 5V4G to give just a bit more punch and output before natural compression of the power stage occurs. Each amplifier is hand wired in our shop in Raleigh, NC, USA.
