[ETO_Alpha] 91b OPR/STBY Switch Not Normal

[Lee Armitage]

Several months ago I noticed that some of the time in a random manner when I
would switch the 91b to standby it would not switch right away as it always
has. Sometimes it would wait a minute or two and then switch to standby. It
always has made the switch to standby, but not right away as normal. The OPR
light stay ON until it goes into standby so the lights are working
correctly. All other functions of the amp seem normal.  Ideas or suggestions
welcomed and appreciated. Thx and 73, Lee in Colorado
