IMHO, a better choice would be a good quality backup power supply for computers which has an inverter built in. That is what I am using for my system. Mainly for protection from lightning but also filters the A/C.

Maybe you would be interested in this: I have an Acurus 75w per channel solid state amp purchased in mid 90s and a Transcendent grounded grid tube pre-amp. I lost both channels at once into a haze of static then silence. I suspected the power supply on one or the other but they checked out ok. I called Acurus to get a price on repair, they have a flat-rate of $250 to refurbish the amplifier plus shipping. It could probably use capacitor refresh . The pre-amp can probably be checked out in a local shop since it's a fairly simple 3 tube circuit. The filaments are glowing on all three tubes, it could be something as simple as the driver tube. If you want to pay for shipping they are yours. The amp weighs about 50ibs. You can get more info on the preamp on this forum: https://tubehifi.websitetoolbox.com/search search on grounded grid. I have enough projects on my list, If I can get rid of these thats two less.

Thanks Dave

I have a Shiit Bifrost that is the initial version to come out. It has optical input and is in good condition. The unit is fully upgradeable. Make an offer quick. it's getting dusty.

I've got a pair of K77s square magnet tweeters that came with my Klipschorns. Both work.

I've had many computers fail. My slide rule still works, glad I don't

DeanG - 16 or 8 ohm? I'll be using the ALK gentle slope. Al says his xover accommodates either one, but somewhere along the line I read that the 16 ohm is a little softer.

Had a number of $100 cars back then, one that comes to mind is a 1966 International pickup truck. Both floor pans were completely rusted out and replaced with plate steel. The points at which the door hinges were bolted also rusted on the passenger side also rusted out and the door fell off. I had a buddy weld the door closed. That cost me an extra $20 each year to bribe the inspection technician to pass safety. Aside from the rust issues that was a good quality truck, Lasted several years. Another car I had was a dodge challenger, I drove it for 6 months and the rear leaf springs went through the trunk. I lifted the car and put a 4x4 piece of lumber between the springs and body. Good to go. I filled the engine weekly with used oil from a local gas station. A great thing about $100 cars was you could always get $50 for scrap towards your next one.

Crossovers with defective components? Unlikely since speakers are tested prior to shipment.

Clean the windshield and check the oil please and give me a dollars worth of premium.

Someone has to pay for Covid-19

Congratulations on your retirement! My present to me was a McIntosh MA352 in February.

Got the J&J and the only side effect was ache at the injection site. I caught covid last Nov which is probably the reason I did not have the usual side effects

I purchased a McIntosh MA352 for my Khorns. An integrated amp with tubes in the preamp and SS amplifier. Nice feature is the preamp output to power an additional amplifier.

Joe - I am needing to upgrade the crossovers in my Khorns and would like to ask what makes you want a pair of VTK-400s vs ALKs crossovers? I am on the fence between Voltis and ALK's gentle slope crossovers. I bought the mid-range horn from Greg and am also planning to buy the BMS 4592ND Mid. Thanks, Rick

And allows you to turn it up again!

I have someone interested in the K77 tweeters from my 1987 Khorns. Can anyone tell me what a fair sale price would be on these items? Thanks K77_Driver

And maybe a bigger house?

Humor me! I was referring to the nuts and bolts on your amp . I am working on a 300B OTL amp for my Khorns. I've run into two problems. I seem to be out of space in the chassis for the big caps in the bridge rectifier circuit and I've developed hand tremors which makes soldering difficult. Four 300B tubes per channel will produce 1.5 watts which should be adequate for Khorns. DC filaments will eliminate any hum from the tubes. Three cabinets, one for toroidal coils and one per channel.

I have a pair of square driver K77s that I just removed from my Khorns. 1987 vintage.

Noticed that those registration cards, postage is paid by the addressee. Get a warranty and don't have to buy a nickel stamp.

Looks like a Franken-Amp. Not really, good job.

Electronics Dysfunction? Not if you change your tubes regularly.

Deang - Your reputation is better than mine.

The Crites B&K A/4500hz. I initially suspected that the network was not compatible but Al told me that the DE120 and the CP25s were interchangeable. The reason I wanted to change the tweeter is because on my invoice from Crites the tweeter was listed as a CT125. I called over there and was told that they were out of CT120s. When I reinstalled the tweeter I got from Crites I read the fine print on the driver and discovered that they were DE120s. So the tweeters are now mounted on a motorboard for a CP25 with a 1/4" piece of plywood reducing the opening. I am going to replace the plastic horns with a pair of DaveA's SMAHL V2.
