Premier 11A mono mod?

Post by ducati748 »

Hi folks

I'm new to the forum. I'm looking so see if anyone have done a bridge mono mod on a Premier 11A. I'm in the process of building a 3 way active crossover speakers. I currently have 1 premier 11A would like to have that modified into a mono block, will eventually pick up another 1 or 2. I'm looking to run tube amps in the mids and highs, solid state for the low end. This is a large box with all JBL pro drives and compression drivers horn for highs.

I haven't called CJ yet but would like to see if anyone have had this done.

Hola ducati748. I do recommend to you to write to Conrad Johnson, addressed to the service Dept, and ask them what do you want to do. 30 years ago, I did a mod for my beloved MV-50s. I took one input resistor to ground with a value of 100K ohms, and connected both channels together right at the input. Because they were connected together, the input R or L would be the same. At the speakers connector I did put two jumpers, from 16 ohms L to 16 ohms R. Being them bridged, the total impedance came to 8 ohms. (parallel connection). Also another jumper from C L to C R, and used the 8 ohm tab. This way I got the power that I was seeking. The sound was better without the bridge mode, but this way, I got the guts that I was seeking. But ask them if you can do this to your amplifier model. They are very handy people with the right advice! Happy listening!

Great suggestion Nando22. Here is jeff Fischel email address: jeff@conradjohnson.com. Write to him and find out more about costs and mods for all Conrad Johnson gear! He is a very humble, handy man! Conrad Johnson now its offering to all C-J goods, the possibility to up-grade for a much better sound! Happy listening!
