What do I need to do to paralled two 35's for use with a small solid state homebuilt amp? Thanks Murray K5MDM Please email direct to You need to find a way to make them share the load. If you just hook 'em up, it's likely that one will be in current limit at a current that exceeds the long-term capability of the supply, while the other one will be loafing...at least until the first one burns up. If it burns up shorted, poof goes your amp. YMMV. mike -- Return address is VALID. Bunch of stuff For Sale and Wanted at the link below.

You will have to isolate the positive terminal on each of them with a high current diode. If you don't you will blow out the 723 IC on the circuit board inside the Astron. Another way is to make sure that both supplies are turned on before you hook them up to each other. You're not going to damage anything else but it's a hassle to replace that IC if it is soldered in. I put a socket in mine. I found this out also when I needed to charge my car battery. Don't hook it up to the battery unless the Astron is already switched on. I have done this with a solid state amp and it works fine. |

Murray, I think you would be better off to get yourself a deep cycle
lead acid battery, or gel-cell battery, and then float it off a charger. |

Murry is not too bright. He might try it.
