After doing my White Oak mods to my PL400 I've had this strange urge to build me a ST-70 kit. I'm hoping the urge passes because $900 for 35W/channel seems a little crazy, but I haven't heard tubes for quite a while.

Loved them for the most part in my Counterpoints. May have to try something again sometime. A friend who is supplying me with a bunch of files has a nice tube setup driving some big-ass Vandersteens that is most excdellent.

A few years ago I gutted and rebuilt the Heathkit AA-32 tube integrated amp I assembled in 1968. Cost of the rebuild was somewhere around $340. When new, the kit was $70 CAD - 8WPC.

Four NOS 6GW8 output tubes were $130 CAD and the price quoted in the assembly manual was $1.25. Two of the originals had gone red plate so I thought to replace all of them.

It's neat to have it in running condition but can't say tube amps are worth the expense. Depite that, I wound up with an AGS Trio receiver that cost maybe $12 but not a single tube inside as I dscovered after purchasing - one of those MaxSold offerings.

It weighs a ton and concensus is 12 to 15 WPC. Got four new Sovtek 6BQ5's from Jim McShane for it's ouputs and did (nearly) an entire recap. All the other tubes were obtained "here & there".

I'm well over $200 into it and it's still a work in progress. During the recap process, one channel on Phono was lost. Probably knocked out when poking inside the rats nest of wires while doing the re-cap. Not a priority now but will do more investigateing....sometime.

I don't find the dollars per watt ratio for tube gear to be particularly attractive. Being involved with audio gear as a job for as long as I was, presented opportinities to hear a good bit of tube gear. But I have to confess, it elicited yawns on my part. And a headshake or two at the expense some will undertake to own a tube rig.

But if I had unlimited funds, I could see myself seriously considering a couple of those mamoth mono tube Carver amps. They look awsome.

I love the sound and I love building tube amps. My 300B amp cost a lot of money to build from scratch, but I saved a bit on some chokes I had around, the chassis is actually an old alarm panel I swiped from work, the filter capacitors and a lot of the couplers are 600 volt PIO motor run capacitors I bought surplus. The transformers are overkill, the power transformer is rated for twice the current the amp uses and the outputs are good to 25 watts each. I may put some mesh plate balloon shape 300Bs in it soon.

I may also throw together some kind of buffer as I might bi-amp soon, maybe build a 2A3 or 45 SET amp or something wacky like that to run some high efficiency super tweeters. I do have some 3k:8 Transcendar OPTs laying around.
