Quick capacitor question

[rocco gibralter]

Ive 2 film caps in a preamp, 152j = 1500pf 5% right? according to the shema the only size other that would be these caps is marked 670pf...

the only other markings on them are 2a09, And they look polyester film, green type.

I swapped these for 2 wima foil caps @ 1500pf, sounded awful!!! so the value must be wrong?!?!?

Seached the web without conclusion ...

PLZ help!

What makes me suspicious, is, there are some 104j's (100.000pf ) just down the track of the exact same green ilk about ten times the size!😕

hello.
152 =1500pf =1,5nf. if they are darkgreen it could be a mylar cap(foil cap,made in japan,taiwan or so).
perhaps it helps..........
greetings......
