Yo, I have been given a chinese headphone amp, the valve in it has a good top end but the base sucks. It says it's an PCC85 but i doubt it really is. I don't know much about values so what can I replace it with for better sound?
Thanks /g/

This
Also tube amps are the worst meme. Solid state amps can recreate the sound but specifically don't because it's fucking garbage
>>61730139
better sound meaning the bass isnt taking a shit.

It was free though so worth a shot.

There is more to it than changing the tube. Without a schematic of the amp, theres literally no way to help you.
>>61730248
totally not going to happen on tubes. That's a VHF tube designed for TV's and rf applications. no wonder it sounds like shit.

so could i replace the tube?

Ask headfi. /g/ is full of poorfags who don't have money to spend on audio

you will have to Google it, no one knows 100s of tubes, and their replacements off the top of our heads. It's old and rareish anyway.

>doesn't actually contain a valve

don't mind the dust

trying to compensate for something with that knob?

let me see some gutz
>>61730964
lol
it's self made, it kinda fit the potentiometer without having to cut it, that's why it's big
>>61730999
veroboard because it's easier and basically yields the same result
can't show much more since it's pretty compact, as you can see the case is not huge

I wanna make one now
>>61731126
I'd give you my schematics if they were not long gone :(
But you can find simple tube amp schematics like this online, and making one probably won't cost that much either. For me it was about $150, but I bought the best of everything, like $2 resistors instead of $0.10 ones and don't get me started on the caps.
Honestly you could probably make this for less than $50 if you have some of the basic things like wires and tools already

this should be very similar to what I have, uses the same tube and other components appear to be similar

id love to see it

My old sony amp worked fine, but after I moved and set it up it outputs at a very low volume. I didnt drop it and its outputting low volume both through the speakers and headphones and both with my ipod through aux and record player through phono. Any ideas?
