Anybody seen these air filters for the
Crown Macro Reference ?

You've probably seen this old 2010 link. Call Crown or get some open cell foam locally.

Macro-Tech are the small amps. I guess I could call crown but would rather not.

The reference is the big boy. ClassA

Home Depot carries the Reticulated Foam for dehumidifiers n shit so I'll skip Crown.

She's a beast. Maybe I can find time to get it going. It has a channel out.

 

[George S.]

How's your Krell coming along?

Didn't know it was class A.

Have not had a chance to look at it or anything as of yet. Too many other projects.

 

[George S.]

I know how that goes.

The Krell is sitting here in line too. With the Slow Start board being a bit toasty I may just off the amp for parts. I rebuilt the L & R amp boards but the old shitty wrong skizmo for the slow start is not helping so I may just find a Krell dude and off it.

I'm chomping at the bit to get to work on the Rek O Kut and I need to finger out what comes next. Maybe I'll dump it all and get another Close N Play

 

[J!m]

Those close n plays aren’t getting any cheaper!

You got that right Jim.

Joe, how did you know it's class A

The original Reference 1 was a dual power corded Class A beast. I also believe when they moved to the next generations, they moved away from Class A to a bridged output approach. I think you have one of the successor generation Reference amps.

Most everything I read, never mentioned one way or another. One guy said Class AB. IDK one way or another. The Operator manual and Service manuals may say.

You have the macro reference from the photo you posted. The Crown Studio Reference was the predecessor big boy

When I was a bench tech at Sound Values, they literally bought a semi load of crown amps that were pulled from MRI systems. The audio version was the MA10,000. The output would go down well below 1 ohm. It was a bridge amp that had 4 heatsinks for the outputs. As I recall each heatsink had 10 outputs in parallel. I had a cut sheet where they claimed one amp powered the entire 400 speaker PA at Indy. There was lots of protection circuits for R.F suppression and thermal issues. They weighed about 125 pounds and ran on 3 phase 208 volts.

There was so many of the amps that spare parts were not an issue. I just changed out blown outputs and swapped boards.
