Red line 60 and 140 cross over help needed!

OK

Basically I am currently looking at Jantzen MKT metalized polyester film caps. I don`t know how well regarded these are but they come in 2 diff. voltage ratings and are cheap.

I think to replace the original 63v caps with 160Vdc caps..so 3.3 and 10uf @160 Vdc

and the 100v rated caps with 250 Vdc caps..so 6.8 15 and 33uf @250 Vdc

Do the voltage values sound ok. If there is a better known brand of reasonable quality budget caps out there what are they and where can I get them.

I`m currently using hificollective.co.uk

Thanks again

Those voltages sound good to me - I agree that you need larger voltage for film caps than for electrolytics. Electrolytics should be the cheapest and most correct choice, as that was what B&O used. But I ended up buying Jantzen Cross Caps from audiohobby.eu. They turned out to be a lot bigger than the old ones, so make sure there is plenty of room, if you buy film caps. Anyway the old caps actually measured okay, and I couldn't hear any difference.

Quick update..I also ended up using Jantzen cross caps, simply because they had all the values I needed in stock at my budget. Ended up using 250 V across the board. The result of swapping out my old Xarus 5000 for the RL140`s and RL 60`s is so marked even a friend of mine commented on the quality..which is something for him. Thanks for all the advise..very happy old man here!

In the mean time I just bought my first full B@O system after 30+ years of waiting. It`s the Beosys 3300 and I`m very happy with it. I know its not their best and lacks some of the features of its bigger brother, but I can`t fault it yet.

I do have a question regarding the polarity of the speaker cables however. I will be running wires in wall, with fly leads between the amp and plug boards on the wall. I`m assuming the flat pin on the speaker plugs is positive? I can`t see any indication any where. I don`t want to solder up all my wall plugs in the wrong polarity

From what I read, flat pin is negative. But it really shouldn't matter as long as you do it the same way on both speakers.

Yes, you are right..a little research confirms it..plugs ordered and thanks.

 

I have a typo in my previous post, my new system is actually 3500 not 3300. I am now on the hunt for a record deck to suit. I believe there is an issue with pre amps  with the later Beo systems? Which deck other than the beogram 3500/4500 can I plug straight in there? The 4500`s seem to be very pricey
