Ohm Model F - What amp/receiver should I get?

I find myself asking a lot of questions already, like what goes into what? my dad has a few crowns, amps and preamps, DC300A, IC 150, D 150A, D 150A Series 2, etc

Message Mapman. He knows a lot about Ohm speakers. And do look at that other Ohm thread. Lots of good info there!

I worked in a stereo store in 1975-6 that carried both Crown and Ohm F's. We had the F's hooked up in our little "high end room," along with Dahlquist DQ10s, ESS AMT 1b's, and a couple of other things. For electronics we carried Phase Linear, Accuphase, USA-made Marantz Pro, and Crown. The Crown DC300A is a fairly good match in that it is high current for its power output (150 wpc into 8 ohms) and very stable into any load. However, we found that the Ohms came alive even more powered by the Phase Linear 700, which is 350 wpc into 8 ohms. In other words, the Ohm F can be a real power hog, but I suspect if your dad was happy with the DC-300A (which was one of my favorite amps at the time), you probably will be too. And we just used 16 ga. lamp cord for speaker cable back then. The same rig will sound much better with today's purpose-built speaker cables.

Parasound63 is also right that there's no receiver I can think of either that would be suitable to drive the Ohm Fs.

As for hooking it up, Crown has free pdf downloads of their discontinued products here. For the IC-150 preamp, click the Line Level link. For the D-150, D-150A, D 150A Series 2, and DC-300A amplifiers, click the Amplifiers link. The D 150 series produces 75 watts per channel into 8 ohms; the DC-300A has double that power.

For example, the IC-150 is a pre-amp. It is the control and switching center for the various stereo components (turntable, tuner, tape machine, CD player, etc.) and has at least one built-in phono preamp stage. You'd plug a magnetic cartridge turntable into Phono 1 and could use the other inputs (e.g., tuner and Aux1 and Aux2 to plug in an FM tuner, CD player, and other source components. Only use the Phono input(s) to plug in a turntable. Then connect (using RCA plug interconnects) the IC-150 preamp to the DC-300A amplifier. You connect the Main Output #1 left and right outputs to the inputs of the DC-300A. Then connect speaker cable from the DC-300A to the pair of Ohm F's. Make sure you keep the positive and negative runs of speaker cable consistent with the positive and negative speaker wire terminals, both on the DC-300A and the Ohm F's.

Download those manuals from Crown and read up on them before connecting or turning on anything. Make sure the volume on the IC-150 is all the way down the first time you turn it on to play music through it. Then bring the volume up gradually until you get to a comfortable listening volume.

Thanks for the input. I'm glad I have been asking around for this sort of stuff, because with receivers, and most speakers, you just plug them in, crank up the volume, not start from 0 and go up.
I will study these instructions and hopefully get something. I don't know what amp is good or bad. I never touched amps in my life. But I'll see what happens.
Thanks again.
If I run into trouble, don't be surprised if you hear from me again.

Once you get the feel for components vs. a receiver, they operate largely the same. It's not a different operating procedure so much as a precaution for the much more powerful amplifier until you get familiar with the equipment and what it does.
