Hey!
I bought my SET amps back in late 1999 and back in the year 2000 my old cat Mr. Bubbles at that time he was about a little over a year old and was full of energy. He likes to run around the room like a tiny cheetah. Well, one day he was running and jumping around, I heard a thud! Not sure if it was something he knocked off the shelf or he ran in to one of my amp, but when I looked closely I saw one of my KR Audio 300BXLS tube bend to one side on the socket and the getter turned white! So, I knew that there's cracked somewhere. Back then a pair cost $675 a pair... ouch!
So, yes I was mad at Mr.Bubbles but of course it is hard to stay mad at him for long after you look at him and when he came to snuggled with me. Anyway, so like you I was in search of a solution. I'm in NYC and back then there was a great plastic supply store down in Chinatown. So, I did some measurement and went down there and have them cut to size acrylic sheets and some glue to build the cover you see in my pic. Funny when I explained to the staff there, he said "I think you're missing one side" Actually, that is right, I left the back open for all the cables. The difficult part is getting bubble free clean look joints which I had hard time with, but so far they still hold.
I take it off when I'm listening to music and those covers serve as my foot rest/laptop rest and the other as a side table. But I left enough room on top that if I pull them out in the front a bit over the concrete slaps for air to go in if I want to leave them cover while I'm using them. I don't remember how much they cost total exactly, but it wasn't much 20 years ago, probably around or under $80. I think the cost of acrylic have gone up a lot since.
Anyway, hope this help and good luck. By the way, a pair of KR Audio 300BXLS or 842VHD tubes now cost $1200! Ouch! Ouch! Ouch! But I do love my SET amps tough.
Buddy
