Haven't looked at it in years now.

Thanks for offering the board.

Here is a link to a 10LZ crossover schematic. Similar to the crossovers of the 12" and 15", the inductor parallels a resistor.

Which schematic did you use? Looking at the crossover for 12" and 15" monitor gold, http://www.hilberink.nl/codehans/tannoy37.htm The inductor parallels the 50 ohm resistor. I read that the resistance of the inductor is important in the crossover design I also read that a lot of people ski...

I'm sure there is a elegant solution for the general topology, we just need to find it.
Just give it some time. I am sure somthing will come up. The two amps that I found utilizing this topology used way too many coupling capacitors.

on paper I have done a number of designs, but I haven't gotten beyond that... mainly since I am not multi-amping at the moment and shines is on the 20 year plan. This is a long term project for me too. So, it may take a while for me to finalize anything. I have been playing with a number of line le...

Just wondering if this set of output transformers was developed? I am thinking something like this for each channel DHT IT (plate loaded) 1st or second order passive filters IT (I have a bunch of 1:1 Altec 15335 octal plug can transformers). So I will probably use them here to three, separate, spud(...

At present, out of PCBs. Thanks for your reply. I will point-to-point your design then. May I ask you a question about the bias? The question that I have are resistor R10 and R23. On the schematic posted on this page, the values are 1K. 402 ohm with the Slage irons. I will be using Slage irons and ...
