FDP Forum / Fender Amps: 1985 - Current / New 68 Custom DRRI Amp "Pops" (loud) on Standby?

New to Fender Electric Guitars and Amps. Picked up a new 68 Custom Deluxe Reverb Amp and every time I switch to "Standby" it "POPS" loudly!

Is this normal?

Please excuse my lack of knowledge here. The Display model I played at the store I do not remember it doing that at all. I called Fender and they said to try it for a bit and if it doesn't stop to return/exchange it. Just thought I would check in with this knowledgeable group.

Note: I always start the Amp on Standby (minimum 30 seconds). When I switch it off Standby it works fine. Only "POPS" when I switch to standby mode. The "POP" is LOUD! Also, the Amp plays/sounds great once it is on.

Appreciate any and all info.

Best,
Michael

Output tubes might not be well matched.

OP -

I bought a new 65 DRRI (wheat/wine red model) earlier this year. Mine also pops when using the 'standby' switch. I stopped using the standby switch and just turn down the volume down at start-up, when switching guitars, and at shut down. No other complaints about the amp...it sounds great...

I haven't replaced the stock tubes yet or adjusted the bias setting. However, I'm not sure that will make a difference. I'm planning to check the 'Eurotubes' site for their recommendation for tubes and bias setting. Perhaps we'll hear from an amp expert here on the forum.

When you turn the amp on just turn the power switch leaving the stanby off wait a minute or so then bring the stanby switch to the on postion. When shutting the amp off turn the stanby to the off postion then the power switch to off. I don't think the tubes have anything to do with the pop it's simply in the amps design and nothing to worry about. It can even be intermident at times.
Leo never wanted a standy switch but added it after feedback from players in the 50's.
