What DI-box to connect speaker out of PRRI to say a Tech21 power engine 60.
Would it need speaker emulation built in to sound correct?
Assuming that I keep the Speaker level out to original PRRI speaker, any ill efects on the amp?

bioblue, I am not sure that I understand the question. speaker outs are not usable into other amps or direct into PA boards. For that purpose one would need a line out with line level voltage as opposed to full blown output voltages. IF the amp doesn't have a line out, then one can be built rather simply; or there are devices that can take the speaker out and provide a line level for hitting another amp or a PA board with a proper signal.
IMHO, a 60-watt SS amp is not much of a 'bump'....but I guess it would provide some volume. I probably would simply mic the PRRi and call it a day. OR...as I say, have a good tech build you a line level out off of the output of the PRRI and you can plug straight into the TEch powered speaker.

The Behringer GI-100 is a decent little DI that gives you switchable cab sim/no sim, ground lift, and two levels of padding in case the signal is too hot. I don't think your tech could deliver all that--in a pretty aluminum case--for $50.

Do NOT plug your PRRI into another amp via its speaker out.
Princeton Reverbs are tube amps and without the proper speaker load on that speaker out jack, you will kill the amp (power tubes, maybe its output transformer, etc).
Listen to Wally - if you really must have a proper Line-Out from this amp, a repairman can install one for you.

Use a Hughes and Kettner Red Box, and send the speaker thru to the speaker of the PRRI. You will love the result. I've been using one for 20 years, and they work and sound great.

I have to mic my rig at nearly every gig. A few times years ago, I used a direct box, but I didn't like the results.The reason to use one was to do live recording for CD and have better control over discrete tracks. It worked, but I didn't like the tone much, and I won't do it that way anymore.
Here's the problem with a direct box from an amp, you'll get some tone from the tonestack, but none from the speakers. A speaker simulator will give you preset choices, but I've never found one that has a worthwhile tone. After all that, you are going to get the sound of the speakers in your slave amp. No matter what you put in, the speakers in the slave cab will color the sound. If they are great sounding speakers, you may get lucky.
Mic the amp, and you have the sound of the amp being amplified by an arguably clear and transparent dedicated system with full range speakers.
If I had to boost the volume of my rig with a 60 watt powered speaker, I would run my guitar through a pedal that has stereo outputs, send one side to my amp and one into a preamp with an EQ control. A cheap tube preamp with or without a graphic EQ pedal may give you a better sound through a slave cab than a direct box, and may not be any more expensive. Anyway, that's how I'd do it.

Thanks for the replies and different views on wether I'd get an equivelent sound out of a DI with an additional non colored power amp/speaker combo.
Obviously I need a speaker load on all the time to keep from blowing the amp.
For $50 I might try it as an option to just have extra headroom for rehearsing with a drummer and keeping up with my lil princeton reissue.
I do have a Boss 59' bassman reissue pedal I can use as a pre amp to use a split signal to the power engine / princeton. That might be an interesting combo as well. But the Princeton sounds so much nicer than that.
For live gigs with a full PA, I'd just mic it with a 57.

Palmer PDI-09 is a great di box design to go in between the speaker out and the speaker. Remember you always need a speaker connected. I have two one in my DRRI and another in my HRDLX. I have used them for years.
