604C Crossover

[Jennifer WhiteWolf]

Greetings, My first post here! I have a 604C in mint condition I wish to use in a mono system I am putting together for my 78 collection. It has no crossover. As I understand it, Doug Sax and his brother worked out a much-better than original X-over with notches for the bad peaks. There are several mentions of it in the archive here. I have also 'heard mention casually' of another design paying a high degree of attention to phase domain characteristics, though I have no attribution or details of it. Can anyone here help with a well developed X-over for my driver, or will I have to test it and design from scratch? I do not wish to bi-amp. Here's hoping for a great schematic to save me a day of futzing and measuring to reinvent a wheel that I am SURE has been WELL covered in the past. Many thanks if you can help! Reference to a web page with the data, or a file sent to me personally is fine either way. If the latter, I can provide an emial address on a Linux machine to send it to. BTW I'll be using a vintage Heathkit Williamson 6L6 amp to drive the 604C, with both a Scott 151, and a Newcomb preamp to choose from. A vintage GE variable reluctance pickup and modern Shure V-15 with assorted styli will do the 'grooving'.

Please note I misspeled my name as a 'screen identity' [ as Jenifer - with one N ] on purpose, as the correct spelling had been taken. I have also corrected the 'junior' thing. At my age, I got a laugh out it it!

Jenifer,

You might also want to check out GuyL's topic below, I think he might be interested in selling his Mastering Labs crossovers.

Hey Dave,

After your visit, I've decided to keep things, just the way they are.
