"AU makes less voltage gain, it sucks more current. But the AX circuit is not designed for this." Artlcle I linked in past post: ""While you can physically use a 12AU7 tube in place of a 12AX7 in a circuit, it’s not recommended to do. Most circuits that are designed for a 12AX7 will not react well to the significantly lower gain of the 12AU7. It can also cause issues with the bias of the amplifier, which can lead to very serious damage, including blowing the amp circuit! The other issue you can run into is the fact that the 12AU7 has a higher plate voltage than a 12AX7, and this difference can cause a host of problems in your amp circuit that was designed around the use of a 12AX7."

"Never swap a AX7 for an AT7. It is simply the totally wrong tube for the circuit conditions. Yes 12AT7 are significantly cheaper than 12AX7, because the demand is high for AX types of tubes. But that does not mean one could replace a AX by an AT. It will be very disappointing." I was waiting for that response and that's why I provided link, not my opinion. "The biggest difference between these the amount of gain they will provide. The 12AX7 has a gain factor of 100, while the 12AT7 has 60. The 12AU7 has the smallest, at just 20." I've swapped 12AT7 for 12AX7 in both guitar and stereo amps. With that said, "I" don't advise anyone to do.......anything (again, that's why I provided link, not my opinion). Paul Grzybek serviced my amps when I began this "hobby". He taught me much. We often traded/bartered amp parts, discussed the latest issue of Vaccum Tube Valley and so on. He suggested using 12AT7 in one instance and not due to cost or availablity, had ample of both on hand.

My Brother severed 25 years in Navy, they even paid for grad school at UT. It wasn’t a walk in the park though. Nice retirement package, he now has second career. I bailed after my initial time was up- coulda, shoulda, woulda. Ample time spent explaining to son the benefits of retiring from military. He's in ROTC and graduates next year.

Years ago I used infrared thermometer when I thought output transformers were running hot. If tubes are biased correctly and not "red plating" I've never thought about it. Possibly operating temp on tube data sheet. Bob Carver sells (current production) "cool running" tube amps which I find intriguing (video of him discussing these amps online). https://www.bobcarvercorp.com In fact, they are the coolest running tube type amplifiers in history, allowing you to actually touch the tops of the mighty KT120's and never be burned! While we caution against grabbing the sides of the output tubes (they must be hot to function), the internal temperature of our amplifiers is a bit warmer than the inside of your mouth, resulting in an indeterminate lifespan. ------------------------------------------------------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------------------------------------------------------ Vacuum Tube Plate Temperature vs Performance In Audio Power Output Tubes.wmv - YouTube ElPaso Tube Amps In working on vacuum tube amplifiers, just for fun, I started measuring the temperature of the output tubes with an IR (infra red) thermometer with a laser pointer.

Most likey due to numerous reasons. One man's opinion: Francis Yared, the credit strategist looks at one of the lesser discussed drivers of inflation and points out that supply shocks to oil prices have historically been relevant for inflation expectations. As Yared writes, "supply shock to oil prices have had a significant impact on inflation expectations on three occasions over the past half century: in the mid 70s, the mid 80s and the mid 10s." However, unlike the infamous price explosions of the 70s and 80s, in the latest episode the "shale oil revolution" resulted in a significant positive supply shock to oil markets which led OPEC in 2014 to defend its market share rather than oil prices. The downward pressure on oil prices, Yared writes, resulted in a shift to a lower inflation regime, which was reflected in both consumer and market inflation expectations (University of Michigan 5-10y and 5y5y breakevens) as well as monetary policy expectations and the term premium. Well not anymore, because ESG is unwinding the shale oil revolution. As recent events at Exxon and Shell have shown, the pressure on oil companies to reduce oil and gas exploration and adapt their business models has increased significantly over the past few months. This is reflected in crude rig counts that have lagged the recovery in oil prices and stand at 1/3rd of the 2014 peak. Similarly, carbon emission future prices in Europe have risen considerably: as the WSJ reported recently, the price of carbon credits traded in Europe has jumped 135% over the past 12 months and recently hit a series of records as economic activity rebounded from pandemic lockdowns. Only lumber, driven higher by the housing boom, has proved a better commodities investment. Another opinion: Why There are Now So Many Shortages (It's Not COVID) - YouTube

",,,,got some klipsch Forte ii in very good condition.They sound lovely but Its my first horn speaker so i have some questions. How different is from iii and iv models?" Forte II- different horns/drivers and possibly different crossovers (slopes). Pull up spec sheet on Klipsch site for III & IV's to confirm. I had Forte I and still have Forte II's. In my opion, Forte I & II's are very, very good performers.

if interested from Jun 5, 2021 : Klipsch Jubilee History - The big one. - YouTube "The last Klipsch History lesson...at least for now. The biggest, the baddest, the meanest. The Jubilee. Brought to you by Paducah Home Theater's very own Cory Harrison. Cory has compiled years of knowledge and insight over the years from speaking to Roy, from selling the units, and from studying non-stop. After several revisions, and several attempts at making this video with corrections and alterations to notes and details, we are finally ready to drop the ultimate history lesson for the Jubilees. From Cory: "The ultimate Jubilee history video. I apologize in advance for the length, I started talking and next thing you know it's an hour later. Minimal notes, minimal cuts. At least 25 maybe 30 major changes and milestones. Feedback and coaching directly from Roy."

At shipping store I've had speakers double boxed. Second larger box is lined and ends sprayed with expanding foam. It creates form fitting foam around inner box ends and corners. You could DIY if desired.
