Very slow, you need to use small value then stated , otherwise it is really slow and old sound. If you have some black beauty, this one is good, and also goodman cap but they are all old caps and difficult to find. I do not like Wima especially on tube amp, it had only Mids and low and high are very week.
the original one is 0.22uf means i get for 0.1 or 0.15uf.
old cap hard to find because i like those old tube n warm sound bcoz i found those new cap all sounded bright n dynamic jensen is hard to find at my country only have audio note but the price is very expensive thanks
