A quick Marantz 2252 tuner capacitor question

[AngelAT]

Happy Easter everybody!

Generally, when I recap a unit, I replace the capacitors with exact uF value, depending what comes out.
Currently I am working on a 2252 (not B) and C307 in the tuner section is 0.22uF/50V in the SM and on the schematic. But the actual capacitor is 0.22uF/50V BP.

What do you guys think: Should I replace it with BP or non bi-polar? And, actually, is it that important, looking at the placement at the schematic (between legs 10 and 11 of Q302?

Thanks in advance!

Probably doesn’t matter. Just get polarity right if using polarized ecap.

I would use a BP cap.

I would use a small film cap, they are non-polar.
Maybe something like Panasonic ECQ-V1H224JL if you can find them.

I've never understood the use of low value electrolytic caps in Japanese hi-fi gear, polar or bi-polar. It's hard to believe they were cheaper, but maybe in quantity when combined with all the other caps from a given supplier. Anyway, like Tom, I'd use a .22 uF film.

Thanks everyone for the replies!
I will check if I have film, second option will be non polar (I have some) and if these do not work I will go for a BP.

Stay safe!
