Did you have anything in mind besides a direct-coupled output?
Well if you are planning to use a tube crossover, my inclination is that the thing to do is build that crossover with slightly more gain than you were planning, and then put a master control in front of the whole thing. Sort of build the line section into the crossover...Well, to be honest, I've been running my system (which I just sold off) with only a passive volume pot going into a Behringer 3400 then to three amps, each with a volume pot to balance the volume between drivers.
So, this whole preamp is new to me. Just before I got ride of everything, I put the Hogan line stage right in front of the 3400 and the system really came alive.
So in the new system I wanted to include a preamp/line stage.....if there is a difference.
I am building three amps at the moment. A 12HL7/GM70, a PP E-linar 807, and a Tim Mellow OTL.
I am also building a three way tube crossover.
My speakers are the big Heil on top, a large Tractrix horn with the TAD 4001 for mid, and a vented box with TD15M for midbass, and a pair of subs with Martin Logan Sub drivers.
I am using a passive volume pot/selector switch before the pre.
SO, I could use some advice as to what to include in the preamp.
I am glad to hear your report about the tube crossover, please let us know how yours turns out.HI DT, If you asked me last year, I would have agreed with you about tube crossovers, but a couple guys around here built the Steve Bench using The Planet PCB and REALLY good PS and they sounded better than the other actives I've had. They are 12db sloops.
The chassis is very steam punk and I am looking forward to starting the build on that.
