Here's one you don't see every day. An Engl Straight 100 from Germany... with a schematic from Germany.... in German. The power and standby switches had both worn out and needed replacing. Both are conveniently tucked under the power supply board, so you have to remove the whole board to get at them. I really wanted to salvage the unique original switches but ended up replacing them with modern parts (sorry bakelite!) After a good cleaning and some fresh power tubes we were on our way. The front panel offered a nearly endless variety of tones. From sparkling cleans to metal crunch and everything in between. An EQ bypass switch on the lead channel provides a unique wide open tube tone. A weird amp for sure, but one that I'm glad I got to experience.
