I have a 100% stock never blown 400 that is very clean cosmetically for $275. You probably would not need your faceplate. This one has had 2 owners, the second of which bought it from me to run his whole house system. he converted to a zone amp and needed more channels. I can't remember the...

Two things to evaluate on any 400; are the output transistors under the heat sink covers original? Is the circuit board inside brown or pale green? 400s blew up so often that most have unmatched output transistors installed. The brown circuit board also blows up, green is the factory...

He was talking about the finishing touches on a bike project, and I said "great, now it is ready to sell!" Nope, Stephen keeps the bikes for his collection. Now I wonder where he has room to store them? If you are a fan of Antique Archeology on tv, some of these bikes are worth some money.

Orange and Stuwee both stood out on AK (or was it TH?) and both were banned. Stephen told me today that banning was a rite and led to great friendships.

Stuwee was the artist among us, helping us be sensitive to the emotional side of this crazy hobby we all love.

1 mA at 10kV will stop a charging bull.

I believe the tweeters (4 triangle thingies) are all piezo. I did not realize the speaker is open baffle! Room placement will be a challenge.

Both your offset numbers are essentially zero. DC offset is influenced by thermal conditions and the matching of the input differential pairs. Emitter resistors have nothing to do with offset. Typically you let the amp get up to operating temperature, then measure. This design takes care of...

In crossovers you need high "power factor" because the capacitors actually heat up! Since no one publishes Power Factor specs, you go with the highest voltage, largest size you can get your hands on. Fulton liked to use 1kV oil filled caps in his monster Fulton Modular Monitors. (he also used...

On a single ended amp, tube rolling will produce differences. I would personally save a set of Telefunkens for a phono preamp.

I have an assortment of premium 6SN7 tubes, and the industrial equivalents, from an estate I'm helping liquidate. If you let me know what price range you are in I'll see what choices you have. Typically the A designation is for tubes with tighter Gm specs. The 6SN7 variations have more to do...

Y'all can just switch to Moon Pies any time you want.

We discovered that bleach will make a black paper cone Pioneer CS-99a brown. I would think dilute black acrylic paint would work fine brushed on.

I wasn't aware the ST-8 existed. The turntable is ok but it must be perfectly level! By adding a wing to the adjustment screw they became much easier to dial in correctly. If you guys want a linear tracker I have an ET-2 arm with pump on a SOTA Star Sapphire vacuum turntable, local pick up only.

Contact the people at AUX33 a used record store. They sell some electronics and I'm sure they ship albums (this store has many reissues and used, and their used prices are great!) so maybe you can talk them into helping. If they ask who put you on their trail, tell them the tourist who yelled...

Not to mention the 200 watt booster EQ amps you could add to your car radio...

How about Audiomavyn on Tape Heads? He's in Montreal and is a service technician. PM him and say that Nakdoc volunteered him to ship the Sansui.

It is possible to have shorted windings caused by insulation failure. If you feed 20 volts AC into the good primary and get 20 volts on the "bad' primary, something else is wrong. You can't operate a transformer with any sort of winding short because it changes the mutual inductance.

I see MMC20E and 20EN cartridges on ebay. It is the 20CL that rarely shows up. The good news about these is the diamond takes much longer to show any wear at all because it is highly polished.

As I read it, you need to send them your BG4002 or BG4004 turntable. The photo does show a different control button layout, and what looks to be a different cartridge! The stupidest thing in the world B&O did was to discontinue their cartridges. I have a couple of these in my back room if...
