IF I had the actual schematic, from THIS amp, I’d post it.
Turns out it was from a line of dealer samples (freebies) without ANY other details like serial numbers. There was a writeup on the amp from 6moons around 2010 with what looks like this identical amp (with small changes regarding IEC socket/fuse only), this is a little older, I think.
The closest schematic I can find so far is this one (with a couple of minor variances like a 5Z3 rectifier, some resistor differences - 1K 25W at the 300b cathode bypass - a 1Uf 450V coupling cap instead of .22 and the PS caps are 330 uF/450V x2 with another 47uF in the chain.

The question is more like, “from what the engineers at TEKTRON chose for capacitors, what are the SPECS on THOSE caps? In this case, US-made TECH-caps,which are no longer available.”
Thanks.

Do you think it is right to use this capacitor at the audio input of the amplifier? Or what to use?
Hi, For non polar input coupling, nichicon ES will be my very very obvious choice and not such wima polyester ones .. nichicon es is cheap and nice sounding unless ypu can obtain and willing to pay for unobtainable red blackgates. Cheers.
Sorry but I am a bit confused .. what amp ?
What is original capacitance and voltage rating ? Pls use same capacitance of what you are trying to replace while voltage rating can be next step higher but never lower.
Use wire ? There was a bi polar capacitor and is for input coupling ? Please use capacitor as designed and needed.
Cheers.

I'm asking about the audio input capacitor of an amplifier I made myself. This is the schematic, which capacitor do you think I should use in C1?
Oops .. I cannot advise since not electrically trained but you must have taken this from designer and strongly recommend you to follow it with capacitor.
Shown wima polyester will surely work but again, I also strongly recommend Nichicon ES for non polar input coupling .. cheap and not difficult to obtain.
Sorry that I cannot advise further and someone else here can do so 🙏🙏
