Welcome to the new home of The sunn Forum!
I sometimes use a Hartke 410 XL with a 200S or 2000S head and they sound much better than I think they should. Impressively loud with the 60 watter, and plenty of stage volume with the 2000S considering the relatively inefficient Hartke drivers. When I use an active bass however I've got to watch the basses output level or it gets kinda nasty sounding fast. I bet it would sound pretty good with both Hartke cabs at an 4 ohm total load on your old beast.

I'm guessing I should plug the 410xl into the first jack, or does it matter?I have a gallien kruger 800rb on them now, but it sounds so wimpy and I can hardy get a good overdrive without usinga bass POD rat channel...or Pi -type channel. That's solid state though I guess.Guitar cabinet wise I was gonna run the 1200S through a 4x12 marshall cab (8 ohms 120RMS)...is this too small a cab?I have a 120 watt solid state marshall head on it now, and it has hardly any bottom whatsoever. Should I mix any solid state effectsfor guitar or bass with it. thanks

If you don't know and they aren't marked, find a tech who can tell you how the jacks are wired to the output transformer. Tell them what you are doing and they can show you how, or rewire them to the appropriate output transformer taps. Experimenting with speaker loads on tube amps can get expensive, you probably should try to get it right the first time!The 8 ohm Marshall cab should work fine with the 1200S, assuming you get it wired to the 8 ohm trans tap.(see above)
First off, this is the old, tube 1200S, right? If it's the newer, Fender-era 1200S with the solid state output, then none of this is applicable.The output transformers on the old Sunns have three outputs: 4, 8 and 16 ohms. They had only two output jacks, though. the way they were wired, there was one main output, either 8 or 16 ohms, which was determined by the cabinet the amp was sold with. The other jack was wired to the next lower impedance, either 4 or 8 ohms. It was also wired such that, when a plug is inserted, it switches the other jack to the lower impedance. So, if you have one 16 ohm cabinet, you plug it into the 16 ohm jack. If you have an 8 ohm cabinet, you plug it into the 8 ohm jack. If you have two 16 ohm cabinets (total 8 ohm load, in parallel), no problem. You plug one into the 16 ohm jack, and the other into the 8 ohm jack. The internal wiring puts both cabinets in parallel, connected to the 8 ohm tap on the output transformer, and everything is fine.

Let me clarify....so if I have two 8 ohm cabs, a harkte 410 and 1x15 in this instance, I can only plug in one cabinet into the second (8ohm) jack....or can I plug both 8ohm cabinets into both jacks at once it will run them both at 8 ohms, and thusly be ok?? Sorry about my ignorance, but I'm pretty new to all this. thanks

If you want to run the pair of 8 ohm Hartkes, ideally you would want to get the outputs connected to the 8 & 4 ohm taps on your output transformer, and plug one cab into each output on the 1200S. Or you could rewire the jacks on your 410 from parallel to series (if you have the "XL" series Hartke 410 there are a pair of jacks on the back wired in parallel, I'm not sure what the "Transporter" series 410 has for jacks) and daisy chain the 115 to the 410 and then into your existing 16 ohm output on your 1200S.

Some say that's not going to hurt the amp. With the price of output transformers, I wouldn't take the chance.The 4 ohm tap is still there, inside your amp. Why not the output to 8/4? You can do it yourself, if you know what you're doing, or any competent tech can do it in a matter of minutes. Or, have the output jacks wired permanently in parallel, and have an impedance selector switch installed.
