Default Jaycar polypropelene capacitors

Hi. I'm currently building a preamp, and I'm still to purchase the 1uF input/output caps (the design is Rod Elliott's project 88 and 06).
I don't want to spend too much money, so I was wondering if Jaycar's "high quiality metallised / polypropelene crossover capacitors" would do the job ? They're relatively cheap, and even though they're advertised as crossover caps, surely they'd suffice at the preamp level?

I live in Australia, so if there are any local sources for quality caps, please tell me!!! The nearest one I know of is in Western Australia (and I'm in VIC!!!)

<a href="http://www.speakerbits.com.au/">Speakerbits</a> in Port Melbourne have 1uF/400V Solen fast caps for Aust$6.00

My Jaycar catalogue lists 1uF/250V P.P. for Aust$2.60.
<a href="http://www.wescomponents.com/">WES Components</a> list a 1uF/100V P.P for $0.96 from my 1999 catalogue.
As to sound???

Hope this helps
James

I have built the 06 phono amp recently and I used the MKT Miniature Polyester caps (as shown in the picture in the article) from Jaycar. These seem fine, but I am sure the crossover caps would be alright. They will obviously sit-up a bit.

Let us know what you think of the phono stage. I am interested in building the 88 pre-amp also.

BTW I used OPA2134 Op-amps. I recommend them.

Hopefully I'll be finished within a month or two. I have almost all the parts, but I have no time (damned uni exams )

I'm going to build the P88 too. Just finished the power supply. I have some rather big 1uF 250V MKP capacitors. I think they will be good enough. The complete code is:

1u0 J 250V BC
378 MKP HQ 02 04

Can anyone tell me what that code means?
