Anyone own a Krell 2250 or 3250?

CH46E · February 25

I just purchased one off Reverb. Should have it in 5 to 6 days. A 3250 that is. I read great reviews.
I got it in part for being stable to 2 ohms for my unfinished infinity RSII. Right now Im running my recapped RTA12Bs. Im hoping for a good bump experience. I will start with my Yamaha Aventage HTR as a pre. Then move over to my Anthem (Sonic Frontier's) tube Pre2L. Was recently serviced .
I honestly think if I don't get a hair raising experience I'll sell everything and buy a sound bar. 😂

I sold my Hafler XL600 local for a fair price.

Just curious if anyone has experience with the Krell 2250 or 3250 amps.

I would probably skip the avr as a preamp, I used a marantz sr7007 for a preamp with my krell ksa 300s and it didn't even last a whole song, way too bright. I would use the sonic frontier's to start with. I use a tube pre with my krell, it gives you great detail without the brightness.

Second that… my experience with Krell is that they tend to be hyper detailed, but also lean towards the brighter side of things. Definitely get some tubes in the mix asap.

When my pre amp was serviced he stated the RCA inputs and out puts were not a standard size. And he was unable to replace them. It made sense to me because all my cables (AQ, Monster, Emotiva and mono price cables fit loose. I was thinking about getting some thin jewelry grade 14 or 24k gold fine wire and hammering it down to thin pieces and placing it around the RCA fittings. Or is there another way I could remedy this issue? I'll use de-ox-it gold on everything prior. I'm not sure I want to open up and play with the fittings in my AQ RCA cables.

Also, I'm guessing the top of the case (that looks like it's a separate and easily removed) has some cosmetic issues. Like the metal all looks straight and I thinks it's anodized black aluminum. Can y'all recommend a fix for this? I was going to look into any local anodizing places to see what they can offer. This amp will be on its own shelf with nothing on top so it's going to show badly.

I don't understand why he couldn't replace the RCA connectors on the preamp

VR3 · February 26

Yeah makes no sense

Does he own a drill

He said something about how there were made. 4 wires each and he could not even find the rights ones or something like this.

Here is a pic of the damage I need fixed on the amp.

invalid · February 26

Does that preamp have HT bypass, it could be the reason for the 4 wires.

VR3 · February 26

The number of wires shouldn't matter. A rca jack only has 2 potential conductors to my knowledge. You could connect as many wires as you want to those conductors

You can try this:

Or a black sharpie...

I'd monitor the auction sites for a parts amp and swap that cover with a good one.

Strip the paint and take it to your local powder coater. They would probably do it for 50 dollars

Maybe I missed it? What was the outcome that required the 2L's repair? Interesting...I used BlueJeans Cables and MIT's (Shotgun series) on the Anthem and don't recall having problems w/connector fit. It was primarily used w/a Parasound HCA-1500A and Sunfire 300/2. First I've read of this on the 2L. The MIT's have a grip collar that tighten...so, that's probably why. Don't have any BJC's in front of me but, as a I recall, they are a fixed diameter. I'd reach out to Chris Johnson @ Parts Connexion to see if he has any suggestions or mods.

Don't have experience w/Krell gear but agree w/other comments above that the Anthem and tube rolling would be the combo to go w/if the Krell's a bit aggressive. From memory...you picked up a pair of the National Panasonic tubes? I have a few pairs for my BHK and would be my recommendation as a starting point if you do.

SCompRacer · February 26

You speak of the Pre2L RCA's? Aren't they PCB mount on a vertical board at rear? They have multiple mounting pins out the rear of RCA block instead of the typical horizontal board, right-angle mount.

Like this...

Not sure. I'll have to take a look when I get home. Thanks though!!! I would have never thought of that.

Thanks! I called and left a message with Krell asking if they have any parts available. Waiting to hear back.

I've not played with it too much since getting it back since I soldy last amp. Waiting for the Krell to arrive. But I'll play with it a bit tomorrow. I took my rcs cables and shot some detox it in then and let them sit for the day. I looked at the AQ Columbia cables I have. They look like a nightmare to take apart. 🤔.

And I do recall seeing the RCA on the anthem mounted directly to the PCB board and there are 4 solder points iirc. Like a circle and then the 4 points like a cross.

Should I be concerned that UPS says the package weight is 30 lbs? This amp is supposed to weight 68 lbs.

VR3 · February 28

Assuming it's the right amp, no they will just send him a bill later

They'll also access a penalty most times.

VR3 · February 28

If he's a frequent offender for sure

mrbigbluelight · February 29

Might be the "30" is in "kg".
That would be a little over 66 lbs, the ballpark weight of the amp
UPS might be talking Canadian instead of American.
🤔

Nah, if definitely says 30 lbs.

But thanks for the responses! Everyone.

CH46E · March 1

Can anyone tell me what this plug is called? Like the terminology I'd need to search to find a suitable power cord before it arrives.

Thank you!!

SCompRacer · March 1

That is an IEC C20 amp male IEC. You need an IEC C19 female cable with the NEMA 5-15P style wall plug. Sometimes the C19 cable will have a NEMA 5-20P plug so make sure you see both ends before ordering.

This is example of C19 with NEMA 5-20P. Notice one male blade horizontal, other vertical. This is for 20amp wall outlet.

If you have standard duplex outlets, this is the one you want.

Yes I did notice. Thanks! Seems like anything I find c19 and 12awg it has the slanted male plug. I guess that's because they are rated for 20amp. I am planning to run from my power box to the wall my equipment is on a 10 awg line. Will plug my power conditioner and the Krell into it. The Krell will go directly to the wall bypassing the power conditioner.

Guess I'll keep looking for a 12 gauge normal us plug with C19.

What's the 3250 rated at current wise? My Krell KSA-250 pulls ~12 amps at idle. It's on a 20-amp circuit.

CH46E · March 2

I'm thinking about this route.

I'm not sure yet. I'll keep looking. I do see power consumption but it's in watts. It has a 2KW toroidal transformer. And I did notice the amp uses a 12 amp fuse on each channel. So I'm just assuming it's designed to be ran on a 15 amp home plug. So id guess somewhere south of 15 amp.

Should I just use a 14 awg standard c19 cable rated at 15 Amps? Or just build my own power cable using the plug in the last post? I have a spool of 10 awg insulated copper wire I could use. For the panel to outlet I'll run a new 15 or 20 amp breaker and 10 awg Romex. I can very easily run a new line at my place.

I did see some BTU ratings on some Krell amps. 😂. Some of them were higher than a space heater!

Anyone own a Krell 2250 or 3250?
