    Schiit Lokius Equalizer with Single Ended Amp and Cornwall II Speakers

    I received a new Lokius Equalizer yesterday from Schiit and wanted to give my first impression on the EQ. It arrived quickly and well packaged. I bought the Lokius to add some subtle bass guitar and kick-drum punch to my system. I'm running a Fluance RT85 turntable with a 2M Blue cartridge...

    EL34 Tube Amp Wiring Dummy Check Please! :)

    One of the major annoyances on my very first build ever, was figuring out all the tips and tricks after already mostly assembling the amp. Drilling more holes at this point would be difficult, and before continplating starting a 2nd build, I would like to get some of these tips/tricks drilled...

    Matching tubes to amps

    Although I have several "valve" amps, I'm only beginning to discover TubeWorld. I don't even know what tubes are inside some of my vintage equipment because I've never looked and wouldn't understand the significance of what I find. Now, with a fair amount of time on my hands, I want to learn...

    The Poor Man's KT88

    Just wanted to share a recent experience. My Jolida JD302BRC can use a variety of power tubes including those usually compatible with EL34 (EL-34, KT77, 6CA7) and the higher powered KT88, 6550, etc. The amp just needs to be manually biased with a multimeter. When I first got the amp, it came...

    How to bias valves on a Dynavox VR-70E II

    Hi, I have one of these being delivered today, and intend to do some tube rolling. Does anyone here know how to bias new valves on this amp? I can't see anything on photos of the amp, or anybody on any forum saying how they have done it. Thanks, John

    New Tubes for Yaqin MC-13s

    Hi all, Awhile back I got a great deal on a Yaqin MC 13s Tube Amp and I've really become addicted to it. I've played with the tubes in the pre section and currently have Tung Sol Ax7's and NOS GE AU7's. I'm finally ready to roll the power tubes. It currently has the original 6CA7's. I'm wanting...

    Name That Tube!

    I've been running my Dynaco ST-70 on some cheap JJ EL34's while I was getting it sorted out, tested, etc. Last night, I traded them out for the ones that came with it. It looks like much of the printing on the tubes has been removed. The 7199's are Tung-Sol, and the GZ34 is labeled Dynaco, so...

    Quicksilver Monoblock, B&W Diamond speaker, Tube Blow

    I have a set of monoblocks (takes EL34, 8417, or 6550 tubes) which I want to hook up to the Bowers & Wilkins 805D speakers. When my output tube failed in the past, my L100 speakers produced a very loud pop sound that I fear might damage the $1k diamond tweeters aboard the B&W speakers. Of...

    Chinese EL34 amp: your opinion please

    I'm watching on the bay a 35W, EL34 powered, integrated amp which seems interesting. Point to point construction and attractive aluminum chassis. It's branded Rftlys model A1-EL34. There's also a more expensive variant with KT88. Never heard of the brand before. Have you ever had any experience...

    Has Anyone Tried the Sophia Electric EL34-ST Tubes on a Dynaco ST-70?

    The reviewer makes them sound like they'd be an improvement over my Soviet tubes. There's a nice article on them here: https://positive-feedback.com/audio-discourse/sexy-blue-tubes-the-sophia-electric-el34-st-and-aqua-274b-vacuum-tubes/ Anyone used these?

    Question about Dynaco ST-70 Original Tubes

    Hi, I'm new to audiokarma but have read a few articles related to vintage speakers and vintage Sansui amplifier. Recently, I pick up a used Dynaco ST-70. The seller claimed that he is the original owner and included the manual. Once I got home and take a closer look at the tubes, I notice the...

    Heathkit AA-121 Restoration

    I just bought a Heathkit AA-121 on eBay for $200 shipped. The guy said that he "plugged it in, 15 seconds later saw smoke and turned it off". The pictures do not show tubes, but who knows if it had them when he tested it. I have an extra output transformer for this amp, so as long as both aren't...

    Looking for DIY Tube amp design

    New to the forum, I'm looking to build an amp in the 25-40W range, and I was wondering if anyone had suggestions for a good push-pull design using EL34s or 6L6s. I'm open to other tubes as well, but I'd like to stick with common and inexpensive tubes (preferably not KT88s). Given that I'm...

    EL-34/KT-77/6550/KT-88 Recommendations

    Hello all, I recently came into a Jolida JD302BRC which I have enjoyed immensely. It came with three quads of output tubes: sets of Tung-Sol 6550, Elecro-Harmonix EL-34, and JJ EL-34. So far I have tried the Tung Sol and the JJ. The JJ were inoffensive but undistinguished, while the Tung...

    How good is AES Sixpacs

    They use 6 EL34s on and 12Bh7 and EL84 on each of the monoblock. Are they really good? I'm thinking of sinking serious money into it.
