  1. Oh, what fun! Just to think that audio has become such an obscure thing. Chicago had a much more diminutive version of Cortland in the west loop, perhaps on Madison or Jackson. Lafayette, EDI and a number of others were there. Allied Radio and Olson Electronics had their big stores much further west on Western avenue. Chicago's little Radio Row stores all winked out by the early 70's as well as Allied and Olson. I was 15 when Allied closed on Western. By that time, the location had deteriorated to the point that nobody in their right mind wanted to go there. In the final days, Allied marked everything down to absolute fire sale prices. I took the L down and returned home with a pair of Jensen Triaxials for $15 each There isn't any place I know of in the states that is similar in any way to Radio Row.
  2. Nah, that's a klipsch!
  3. I recent brought the 2a's back into the rotation. After a bit of use the cone mids seemed a tad lackluster. Thought it would be fun to try switching out with something new. Just tried using hf units from a pair of 80's Philips powered studio monitors. AD 5060/Sq8 midrange and AD 0160 T8 tweeter crossed over at the ar-2a frequencies Sounded really nice, if totally different than the AR's. Going to try crossing the mid over at 800 hz as soon as I get the inductor. Alas, didn't have any 1.5 mh in the stash.... I didn't try mounting in the cabinet, put them in a pair of small Garrard Satellite cabinets.
  4. How lucky you are. Radio is sadly pretty poor in most parts of the states. If NPR isn't ones cup of tea, that leaves just one classical and one low power jazz in Chicagoland. Rock is limited to the top 100 compressed as hell and the other chicago's finest rock station. Forty years ago there was a significantly greater variety in this market and from what I've noticed it's about the same everywhere else.
  5. I had one of those. Really liked it. I regret that when I had it i ran it hard. Replaced most every cap. I used it with KLH 6, which took everything it had and didn't blink.
  6. Having been in the near west suburbs of Chicago at the young age when the HiFi bug bit me, I had no shortage of stores to visit. Within an easy bus ride, I had Allied Radio, Radio Shack, Olson Electronics, Musicraft, HiFi Hutch, Tech Hifi, Lafayette Electronics, EDI (electronic distributors inc.) and this was just in 1971! By that point in time, the StereoSnob sales technique was on the wane, primarily due to the fact that a large percentage if not the majority of purchases were being made by high school / college age customers. Kids would be annoyed and go elsewhere if confronted with an attitude like the salesman was vastly superior to the cretin about to fork over his cash. At that point in time the stores like Musicraft had used as well as new merchandise for sale, as much of their sales volume was stimulated by the fact that a five year old item could be traded in on the latest piece of silicon. My first Scott 299B came from Musicraft in such manner, along with a pair of AR-2's in glorious unadorned pine. The smart salesperson applied a veneer of friendliness since he (no girls allowed at that point) knew that the kid would soon be coming back for a step up in the sonic vistas offered on the carpeted shelves. I'm sure that I wasn't the only kid in the early 70's outfitting not only his bedroom with precious electron hungry hardware, but also his private psychedelic dungeon where sound, smoke and blacklight occasionally escaped but everything else that happened there was uncharted territory to all adults. 3600' at 3 3/4 ips on a reversing reel machine could play for hours to the delight of all who dared enter the magic pit of sound. I really have to wonder where the indulgence, tolerance and forbearance of the denizens of the adult world came from. Now that the audio hobby has retreated into relative obscurity, I would imagine that the supercilious salesperson selling magic speaker cable has returned. When you have to pay for a retail business with a diminishing clientele, maybe it pays to insult the customer again?
  7. I inherited my mom's set of Russel Wright designed bedroom furniture. It was originally blonde, but not with the whitewash basecoat. This was done with yellow tinted organic varnish which became more orange-ish as time went by. In the early 80's she had a local wood refinisher strip and put a medium chestnut 'ish stain on and recoat in satin. The refinishing probably took any value out of them but heck, it made her happy.
  8. When the milky blonde finishes popular just after the war began to fade in popularity, the mid century modern look took hold and walnut and it's woodgrain imitators seemed to be rage of the day. That standard look really lasted a long time.
  9. Even the Better Half says these are the best sounding speaks I have ever put in front of her. And there have been a whole lot of cabinets in our house!
  10. My 3a's are now for all intents and purposes fully restored. I elected not to replace the tweets with the HIVI 4 ohm replacements. These just sound better and better as the days go by. The system most used for music is also the system used for visual media playback. Been watching an English mystery series called Broadchurch. These are REALLY nice for general purpose usage as well as critical music listening. The previous boxes in place were the 2Ax's. Just a world of difference between those and the 3a's
  11. was just playing a darn near mint lp of The Soft Parade through my 3a's. cant get over how nice the drum track sounds through them.
  12. I had found a pair of 4x at the thrift last year. The tweets were both toast. I replaced them with the phenolic ring drivers, Part # 270-252 from Parts Express. Other than being a little brighter than I remembered the 4x being, they sounded really nice for $20 or so each. They are rear wired, so a little re-wiring is required.
  13. Very handy calculator! That's just what I was needing. I connected the 10,000uf back to back DC blocker caps to each other with a pull tie connected old screw terminals and hot melted the whole mess together. I then connected them to the 2Ax's. I disconnected the Scott 477, and connected the Dynaco ST-150 along with the PAT-4A. Both of these just had all the electrolytic caps replaced, power supply as well as signal path. I didn't notice any apparent bass extension or enhancement but was happy to note that when the recently recapped ST-150 developed a cranky condition with errant semiconductors it indeed did exactly what I had intended. The unit developed intermittent DC pops and rustling sounds much like one may hear during shut down of an amplifier. A trip to tri-state electronics for some PNP type 2N4889 should take care of the problem. I didn't have any fuses installed, so can't say whether the AR recommended fuses would have opened with the DC pops. Meanwhile, The Scott 477 ( old reliable ) is back in place. Once again, with or without the caps in place, I don't notice with my old ears any significant difference between the caps or not. Thanks for everyone's input on this! Lou
  14. Given a choice between an active device and some dumb passives, my sensibility leans towards the passives. Earlier in this thread, there was mention of purported low end enhancement with the caps in place. When I place the back to back 10,000uf 100V caps in line I'll post my observations as to whether this may be discernible (for me). I'm trying to understand why that might be so, whether its that the bipolar capacitance in series changes the electrical reactance, causing a lowering of the resonant point. If so, wouldn't that also affect the effective impedance? Lou
  15. Thanks Carl, I'm a bit wary with the 3a's and their weird impedance and the difficulty some amplifiers have with them. The DC-300 is essentially an op amp capable of passing DC as a feature of it's design and if it fails...... Pffft!
