I have a pair of klipsch cornwalls. Is this amp enough to drive those?

DavestefYes, it's all about that first watt, as the saying goes, Cornwalls are very efficient.
Then you will want upgraded NOS tubes and the caps of course, endgame?
Feed it well from a nice DAC and a quality recording, and enjoy.

Davestef With an MM you are OK, meaning sound will happen, a MC high output maybe... essentially these little fellows could be a phono pre-amp but they have no equalization for MC vs MM. Spec says 500mV 10Kohm for this EL34 and 500mV 50Kohm input for the EL84 version APPJ amp,, these are specs.. 500mV sensitivity seems a bit conservative..., you are feeding a 12AX7 preamp tube so...
Short answer; it will work, will make sound, not good sound - no RIAA EQ, but not punch you against the wall, you will still want to have high efficiency speakers i.e. Kipsch ((better for these small amps regardless)). You have Cornwalls, you are fine to test:)
Safer answer, of course;) get a phono pre-amp.
Longer answer requirement; what setup do you have for a table now?
Another possible answer; anyone reading this, tried it? Or just opine-in...
You can see folks are doing it: http://www.klipsch.com/blog/u-turn-audio-orbit-basic-turntable-review
Personally, I have not looked at doing this, as I hope to get: http://www.korg.com/us/products/audio/ds_dac_10r/
Then you get to play with:
"The AudioGate 4 contains a DSD phono equalizer that restores all of the sound that went into cutting the record, while minimizing any effect of the equalization process on the sound. In addition to the standard RIAA curve, five other curves(*2)are also supported. Phono equalization can be applied as you record, or when playing back an un-equalized DSD recording made from your vinyl sources. This versatile cutting-edge technology lets you appreciate the true power of vinyl records in a way until now impossible—even on high-end audio equipment. *1. The record lathes used in the process of producing vinyl records cut a wider groove as the frequency of the sound becomes lower; this makes it difficult for the needle to accurately trace the groove during playback, and also decreases the recording time. For this reason, the record being cut is equalized to attenuate the low-frequency range and boost the high-frequency range, and the opposite curve is applied during playback. This compensation is applied by the “phono equalizer.” Since record players have a lower output level in comparison to most audio devices, it is necessary to boost the signal, and the phono equalizer typically performs this role as well. However on the DS-DAC-10R, the amplification is handled by an analog circuit and the equalization is separately performed using digital signal processing (within AudioGate 4).
*2. RIAA is the standard recording/playback equalization curve for records defined by the Recording Industry Association of America. It became a standard in 1954, but prior to that date there was no standardization between the various record labels. Since the curve is not indicated on the records themselves, it’s not possible to know which curve was used to record a given record; however it is said that nearly all records can be covered by the RIAA curve and five other curves. Try selecting different curves in AudioGate 4 and enjoy the resulting changes in tonality. "

rastusright now I use two 60’s pioneer tube amps that my dad brought back from Japan when we was in the service. But they definitely need recapping becuase they hum and rumble a lot. I picked up a pair of Mcintosh mc30’s that the seller had recently had recapped and they were working fine. I havent picked up a preamp for THem though. So until I find a decent mx110 /c20 /c22. I wanted to get something decent that a thing least doesn’t rumble so much.

DavestefI own an APPJ EL84 / 12AX7 Single Ended.
It pushes a whopping 3.5 Watts MAX.
It pushes my Klipsch RP-150M to ear bleeding levels of volume.
My Klipsch (at 93db) are far less sensitive than your Cornwalls.
This amp should be able to push your Cornwalls to hearing damage levels.
I also run a Rogue KT120 Push-Pull with 100 Watts ... I maybe use 5 of its 100 watts on any given day.
I would run a dedicated Phono Pre (currently using a Schiit Mani) if I were to use this for LP playback.

LiquidSmoteYour idea of ear bleeding loud is a lot different from mine. I have a SET that's about the same power, and my 94db Klipsch KG 3.5's were not nearly loud enough for me in my small room.

amb3cogLOL ... loud enough to cause hearing damage from sustained listening.
Be careful with your ears good sir!

LiquidSmoteI can't do it sustained. I'm old. But I like to for one, or two songs. I actually just put together a real nice system for this reason only with an AVA Omega Star 250EX, and a pair of Cerwin Vega VS-150's. Love to pound the rock, and this does that very well. It's unbelievably loud!
