      Thanks! I strongly encourage anyone capable of uploading their demo to do so, as it will both streamline the event and make it easy to make sure everyone can walk away with demos at the event. I plan on burning CDs with demo complications compilations before the event and they will be on hand to take!

          There isn't enough time in the day :(. I need to quit horsing around with crossovers every moment of every day after work and get after this.

            I've heard of this thing called proofreading. I might even try it sometime. :o

              The swap meet table is really looking tempting. PWR RYD and DougP added more items. Check it out!!

                Just in case someone might be interested, please read Craigk's post (#6) in this thread:


                I hope everyone has a great time and gets to hear a bunch of great speakers in Iowa.
                Thanks,

                      If we all reacted the same way, we'd be predictable, and there's always more than one way to view a situation.

                          Vintage power amps for sale:

                          Hi Gang,
                          They have all been recently gone through. Any necessary repairs were accomplished, and the bias / offset adjusted as required by an experienced electronics technician. -That would be me, of course, so I can vouch for him/me.

                          Each has been run in my system for several hours to verify their operation and sonic attributes. Solid state amplifiers has been a 'mature' technology for a long time, and these amps hail from the heyday when aural qualities were higher on the manufacturer's list than profit taking...

                          If you have any interest in the following, please email me and I’ll answer your questions and bring along to Iowa.

                          Adcom GFA-545 100 wpc 8 ohms
                          $150.00
                          This is the little brother to the GFA-555, which was a very well received Nelson Pass design. The 545 shares a very similar architecture but less power. Nice little amp. Triple BJT outputs.

                          Adcom GFA-5300 80 wpc 8 ohms
                          $150.00
                          A little less power, and a couple of generations newer than the 545. Nice sounding MOSFET amp. Both of these Adcom amps have a nice dual mono power supply construction in all but the shared power transformer.

                          B&K ST-202 150 wpc 8 ohms
                          $200.00
                          This one is in good shape and bone stock. This is an early s/n with the (IMO) better TO3 MOSFET devices. It is identical to the more popular ST-140 of the same vintage, but with dual MOSFETS, and unlike the ST-140 can drive 4 ohm speakers to full power. This design really responds well to cap changes. Put a quality poly cap on the input and a Nichicon Muse BP on the feedback and it really opens up. Lots of room inside for additional power supply filtering as well.

                          Hafler PRO-2400 120 wpc 400w mono -Both at 8 ohms.
                          $200.00
                          Nice rackmout MOSFET amp. It came from Rockford with an IMO, poorly designed balanced input board. I ‘lost’ the cheesy balanced board and modified it for single ended operation with gold plated RCA jacks. This one cleaned up well and sounds as good as it looks.

                          Hafler XL-280 145wpc 400w mono -Both at 8 ohms.
                          $300.00
                          IMO, probably one of David Hafler’s best sounding amps. I could live with this one in my system for a long time. One unique feature is user accessible adjustments for distortion reduction. This one is in excellent shape. Engineering attributes include triple MOSFET outputs, dual power supply construction, and independent, raised power supply rails for the input sections.

                          Not exactly vintage:
                          Parasound Halo A23 power amp 125wpc 400w mono -Both at 8 ohms.
                          +the matching Parasound Halo P3 Preamp.
                          $900.00 for the pair.
                          Very nice John Curl designs that were my reference amp/preamp for a few years. The A23 is in excellent condition and comes with the original box. The P3 has a couple of light scratches on the top where a previous owner had slid other equipment over it, but otherwise functions flawlessly. The P3 comes with the original remote and manual but not the original box. I’ve never popped the covers on these, so they sound just as JC intended. Both are silver faced. The A23 is still in current production: http://www.parasound.com/a23.php

                              Gents:
                              As you can see from the prices I'm just trying to recoup some of my cost in them. My purpose was to get a feel for the sonic qualities of different circuit topologies, and I enjoyed repairing and refurbishing those that required it. The ones I added significant modifications to are not in this group, as I suspect no one would want an amp modded by some upstart from Nebraska, or consider that they could sound so much better than the 'stock'. Those of you who are into building amps of course know many manufacturers cut corners to control costs, and the difference a 'few extra dollars' can make.

                              If you are not going to Iowa, or have no room to haul one back, no worries. I can ship to the US. My freight costs are $40.00
