5/21/1979 and 5/23/1979.

Too new for me! Sorry.

The original K-72 was a Heppner-built unit with a square horn (K-72-H). Shortly K&A expanded their in-house driver building to include tweeters and mids, particularly those formerly made at Heppner. The K-72-K was K&A's first tweeter to build, and it debuted with the round plastic horn.

Production numbers per year would be quite a project, and in the mid 80's when records went digital, the data is incomplete and unrecoverable. Maybe someday it will "come to the top".

$379 each. Sorry for the delay. I really don't do the private message thing.

Very strange beast. I consulted with Gary Gillum (the "g2" in Kg2), and neither of us remember anything like this. It is conceivable that Klipsch Sales had a clandestine (as far as Engineering goes) "pilot run" done overseas...........

Coytee, I'll try to keep the bird at bay (for the moment). In the early days PWK was in charge of all aspects including finishes and veneers. However, he did solicit opinions from staff, dealers, and friends. Early 1950's veneers primarily included mahogany, walnut, prima vera, and raw gum! W/o an exhaustive deep dive into the logbooks (a royal PITA) it seems that oak did not surface until the late 60's. The promotion of "exotics" came well after the employment of Bob Moers in 1961 as the "marketing brains" behind the "technical genius". Obviously one-offs occurred from the beginning. One could send in a Western Electric 555 to be incorporated into their Klipschorn!

The K-33-P and K-33-E were used interchangably for several years in the mid 70's. P for CTS Paducah, KY, and E for Eminence. If the woofer sounds good, I'd just apply a little "Elmer's glue" and rock on.

Without a lot of research, Karlson3 is at least "very close"!

16 ohms is irrelevant. Advertising ratings have changed over the years. The K-horn used to be rated at 16 ohms, but it had a 4 ohm DCR woofer even then. If the caps are not leaking oil, they are likely fine. I'd run them as they are, but have a little discretion on the volume control!

Covet indeed! I could use some kindling......

Sorry, but they are "too new" for my database! Klipsch customer service might be able to help.

JohnA is correct. The labels are not available.

Birch plywood was only used for "decorator" models. It was not used in cabinets of any model with a "fine veneer", unless by some obscure deviation from standard. All products with fine veneers were changed from lumber-core to MDF in the early to mid-80's. I believe the Chorus started life using MDF.

212 and 213 were shipped 17Feb1961. They are the 112th and 113th units shipped, since serial numbers began with 101. The driver complements were the same when shipped, and included the K-22 woofer. If they now differ, it had to be an update or repair. "New style" is noted in the logbook. I believe this means they no longer have the grill cloth on the sides of the cabinets. If that is incorrect, please let me know.

These are very early units, probably prior to 1960. They are the 112th and 113th made. The "b" suffix in the model number may mean they are the "starter model" which came with no midrange or tweeter, just a 12" woofer with whizzer cone. While that would make them "rarer" than most, obviously the performance is a step down. I can look them up on Monday.

To my knowledge, Cornwalls were never made using Baltic Birch, unless possibly as a specific special order. The birch used for decorator models was a custom void-free plywood made to Klipsch's spec. MDF did replace lumber core in the early 80's for models with "fine veneers".

Victor Brociner was one of PWK's first distributors in NYC. We have 2 Brociner units in the KHMA collection. Their relationship appears to have been rocky from the start. Brociner liked to sell components, and mix-match with other manufacturers' parts. Eventually he stopped paying royalties and started ripping off the design. We have about an inch of documentation concerning patent infringement. It appears that PWK did not have the resources to successfully get a cease and desist.

Signatures go back quite a ways. They were usually for "special" customers (dealers, celebrities, etc.) and employees. The coolest one I've seen included PWK and Belle, as well as Bob Moers and his wife. It is on the motorboard of a 1974 Klipschorn. That was about a year before Belle passed away.

#279 shipped 11 Oct 1961. It was at least originally a "B" version which meant no mid or tweeter. The K-22 had a whizzer cone that sorta made it full range. The idea was to buy it as a starter model (cheap) and upgrade later with mid and tweet.

The addition of the "A" to Heresy serial numbers did not occur until August 6, 1963.

Hi Steve. It looks like your question has been answered about as well as possible with the information at hand. It's possible the actual serial number could reveal more, but if it is indeed a 1985 unit, not much more will be available.

Wish I could help, but they are "too new" for my database!

#1030 was shipped to Dr. Wynsen of Columbus, OH on May 4, 1956. Dealer was Custom Electronics of Dayton. It is mahogany and the original components were Stephens 103LX2 woofer, University SAHF squawker (on a K-5-J horn), and University 4401 tweeter. The upgrade included the HF baffle for mounting the K-400 horn.

Paul's first metal horn was the K-1000 used in the Rebels, Shorthorns, and early Heresy's and Cornwalls. This would have been 1950 +/- a year. We have his wooden pattern on display. Paul liked to get his hands dirty, and did virtually all of the pattern making and first-off moldings himself. In the case of the K-400, he first built one from sheet metal and covered it with "tar". It is also on display. I believe it was the K-700 that was plagiarized from one he pulled out of John Eargle's trash can when he worked at Jensen. Otherwise it was all him thru the K-260.
