Magnus A rare occasion that I get to have an answer for you. I have two sulzers also and the batteries 5 years ago were an issue. I believe nimh batteries could be put in if you really need batteries. At $35 I passed that option. Plus batteries are just a pain. I think the issue you have is that without the batteries its filtering is quite poor you need a larger filter cap 2200 uf at the very least. Its 21 V as I recall. The system is indeed intended to charge nicads and so it really is a current charger. But will run the oscillator with a cap.
Far wiser (Which I did not do) is to replace the guts with a regulator. A 3 terminal adjustable would be great plus a bit of heat sink. Though you could use the actual assembly for that with a insulator. By the way the can cap thats is in my units were bad. Good luck great oscillators Regards Paul WB8TSL On Thu, Nov 1, 2012 at 4:51 PM, Magnus Danielson <[email protected] > wrote: > Fellow time-nuts, > > Yesterday I picked up a Sulzer 5A + 5P without batteries.
