Is there any milage in putting a soft start circuit ( the type used for electric drills , circular saws etc , that limits the initial switch on voltage , and gradually increases it ) in the switch on cables in the amp ? Dont know if this can be done , not enough knowledge , just a suggestion .

Hi , Put the above suppressor across the switch contacts ............ Switch on is quieter , and switch off is almost silent ! Pete

I have ordered one of these............

Thank you all for your input . Pete

Thanks for the schematics Bigguy2017 Pete

The black square item , has only two tags connected to board , so it can't be a relay . Have you a schematic of the Peavey T Max then ? Pete

Is this the soft start board in the Peavey T Max. And is the other pic a capacitor . It only has two solder tags in the board, so it is not a relay .

Peavey say they think it could be the mains on / off switch causing an arc during switching giving the pop through the speaker . Does anyone know what resistor and capacitor value I could use for soldering across the contacts in the switch , to stop the arc ? A couple of articles I have read are sayin as a rough guide ........ 1ohm per volt for the resistor and 1mf per amp for the capacitor across the contacts = 240ohm + 16mf . Anyone know ? Pete

A guy at Peavey has got back to me , and suggests that I get in touch with the service / repair guys at Corby , and ask them about plugging in the speaker after switching on the amp . Rang Peavey at Corby , but the engineers are away at some show till next week . The guy on the phone did say that Solid State Power sections do not have an output transformer ( valve amps do ) I'll give them a ring next week . Confused now........ Pete

sandy_r ☺️.........Brilliant idea........thanks........will wait to see what Peavey say, but if they take too long , I will build one......... thats brilliant . Thanks

Volume on zero ( main and pre amps ) graphic switched out . When switching it on / off at the mains , the pop is quieter . I was always told that with Solid State Power amps , no speaker connected is the same as having an infinate resistance ? I`ll get in touch with Peavey and see what they say . Thanks guys

Hi , I just got hold of an old Peavey T Max Head , when its running its quiet but when I switch it on or off , there is a loud pop through the speakers .( Its an old Solid State amp ) The way I get over it is to connect the speakers after switch on . Anyone any suggestions ? Pete
