My Swifty doesn't work, I'm taking it back for a refund! I put it on the equipment rack and all it does is sit there with the dust! Back to my trusty 2 cycle leaf blower. (With proper ear protection of course.)

I've heard of sleep drivers with Ambien. It's a good thing that cars have collapsable columns and inflatable bubbles in case you roll-off the road. Roy, Is this you in your younger days?

I'll get some up tomorrow.

The documentation is sorely lacking in this department! Mine are jumped the other way, 12V and worked. Rick

Glad to see you are feeling better dtel.. Now back to the serious matters at hand. Listen here Bozo we are much better clowns than average!!.

Frank, You have to place a jumpers on the boards at two places. On the board near both tubes you will see three soldering eyelets.A jumper must be connected from the hole connected to hole 6 to the center eyelet connected to pin 5 on the tube on the tube side of the board you can see (with glasses LOL) holes marked 6V and 12V.( I used a cut off lead from one of the resistors) If you are still confused, I'll get my camera back from my wife tomorrow and post pics. Rick

Yeah, that's more like it! 41.5" wide and 24.5" deep. Indy, where did you get the erronious info?

I heard that this will be the only legal amplifier in California. Next year, all residents will have to register their audio equipment of face fines or prison. In five years, it must all be turned in or prison terms will apply.

Jubilee jealousy is catching. AhChoo!!!! Answer me a riddle. The size spec's posted: dimensions 78.3" (199cm) H x 98.6" (250cm) W x 57.3" (146cm) D I thought the Jube's footprint was similiar to a Khorns, not 8 feet wide and 5 feet deep????? I understand that the hieght for home use is lower without the supertweeter on top but............

Sovtek 5U4 Jay. Rick

I have the RCA blackplate 12BH7s in. From what I read, they are the best. There aren't a lot of choices in this tube designation. Definately not like 12AX7s or 12AU7s. Rick

No, it's the same amp, same chassis. I swapped out the PS choke for a heftier unit, eliminated the volume pots, added the black walnut trim and a new on/off switch. I have made so many mods under the chassis, that I don't have a photographic record. Rick

Ha ha. You got me Jay. That's an old pic. Here is one from just now:

George, For a temporary box, go to Wal Mart'sa craft department. They have a 5 sided square box that is just the right size for 2404s (or CT125) for about 3 bucks. It's easy to make the cut-out with an Exacto knife.

FYI: The baltic birch is bendable on only one axis. Make sure you have it right before you cut the tapers.[]

Jay, Those are Electro Harmonex Gold Grids. Without a doubt, the best 300B for the money! Rick

Do I gotta wear these?

I've had Shannon Parks DIY Poseidon boards with Jensen PIO coupling caps running for about a week now. The population and building of the boards is rather easy. With care, a first timer could complete the task in a couple of nights. I bought all the resistors and small parts in accordance with DIY's great bill of material included in the documentation just substituting the Jensens for the metalized poly caps and Uncle Ned's plate resistor values. I also eliminated the biasing circuit on the boards as I had already incorporated an individual biasing scheme in my original build. The only caveat I have for a newbie is to make sure to heat sink the leads on the constant current device in the driver stage as it is easy to damage solid state devices with too much heat. OK, now for the juicy part. I tested for DC and oscillation, which were fine then I hooked them up to the Juicymusic Blueberry Extreme. I turned everything on and the SOUND! WTF did I do to my amps!!! It was that bad!! After a few minutes, things settled in and the sound became better and better and better until it reached the 72 hour mark from where it has remained the same. Running NOS RCA 5963 and black plate 12BH7s and GE 6550s the sound is much smoother and more musical than the stock Mark IIIs from which the transformers were donated, the previous Triode Electronics boards and the "other boards" I initially used in both triode and ultra linear modes. The dynamic punch is less than the Triode boards but then, the Triode boards over exaggerated the punch of a kick drum to a rather unpleasant startlingness. The bass is warm and tight, the mids while not as silky as DHTs are excellent. The highs are clear and pleasant and extend well beyond my hearing. All in all, I highly recommend the Poseidon boards for anyone planning an upgrade to some Dynaco Mark IIIs or a bottom up build using aftermarket transformers. Fini, Robert, did you build up your's yet? Rick PS: I want to try a set of the Valve Art KT-88s Craig has raved about but I can't right now. I've spent my allowance getting ready for this years archery tournament season.

Thanks Craig.) Just the one Jay. Rick

Yes, excellent review burning! Are you sure you don't work for Klipsch marketing???[] Welcome aboard and enjoy your RF-83s. Rick

Can you PM me the phone #? Thanx. The spec's above except the voltages are just guessed at. Of course they would know more than me and I'll follow they're advice. They are the Pro's.[] Rick
