WATCH RELATED VIDEO: KT88 Single Ended Tube Amplifier Build 2018 - Part 10

Antique Radio Forums


Dennis Had is a legendary name in tube audio. The founder of Cary Audio, Dennis has been at the tube business for a long time. Now in his retirement, Dennis builds one-off single ended amplifiers out of his workshop in Cary, North Carolina under his "Inspire" brand.

I've been watching these beautiful amps come and go on eBay for a while now, but all of the Inspire amplifiers that I've seen so far are pure power amplifiers, with no integrated functionality. I've come to the point in my audio journey where I want a volume control on every amplifier; I think more often than not amplifiers sound better run direct than following a preamp.

That makes it the most versatile amp I've owned, a title previously held by the Decware Mini Torii. With a pin adapter, it can take any of the popular rectifiers like 5AR4 and 5U4G as well.

The tube family has a lot of variation and a lot of flavors to choose from. All of this combined with the output tube flexibility makes this little amplifier quite a Swiss Army knife. In person, this is a great looking and feeling amplifier. For a workshop creation this is every bit as clean and classy of a build as I've seen on any tube product anywhere.

This feels robust and supremely well made. Its footprint is relatively small as well, and its not a 50 pound monster like some of the other gear that has passed through here has been. All in all this looks and feels like the true Hot Rod that it is.

So how does it sound? Quite good actually, with the KT66 or EL34 probably being my favorite flavor at this point. So equipped, this Dennis Had "Inspire" amplifier is a very strong performer.

No hum, no static, no issues at all, just super hi-fidelity with a great soundstage, easy to place performers and a voice that is in the room. This may be the single ended 6L6 amp that I keep for the long haul. Highly recommended for the tube rolling audiofool like myself. Super high quality build with teflon tube sockets and luxurious automotive style paint.

Well done! Its hard to beat the look of the early 's blue Arcturus 80 globe. Did I mention this runs EL34 tubes as well? Very clear "live" and crisp sound with these older short base RFT tubes. These sound very good actually, with a warm and richly textured presentation; perhaps a tad less sparkle than some of the others. The early metal version of the 6L6 is a fine tube and still very affordable, but be warned that it cannot handle a circuit with voltages designed for the later 6L6GC.

The hand-grenade sized KT is a big and powerful tube in this amp, here rectified by a Mullard "saw tooth" 5AR4 on a 5U4 to 5Z3 pin adapter. And while the whole picture is slightly "bigger" with the KT, I feel like the image and realistic spacing is better with some of the less powerful tubes like the KT66 and the EL The Sophia Aqua B rectifier is a great performer in my Yamamoto amplifier, but I feel the 80 globe is an overall better choice with the Dennis Had amp.

Size wise they are similar but otherwise its apples vs. If you own efficient speakers, both are sure to please. The KT66 is a top performer in this amplifier.

Kt88 Se Amp. Effects level switch. IDK about that, I have one running in a very similar amp that is set up as a light weight geetar amp. However, some previous experience with building vacuum tube circuits is highly recommended. All was working OK. The electronic design stems from Menno van der Veen ir.

When both pairs of LED are not glowing, the idle Idc in each pair of KT88 because vacuum is nearly perfect, and you may see a feint dark blue glow at.

El84 Power Amp


Handle with care! When operational they are hot! Only Crack the Volume up after an good burn in period Built this custom one off guitar amplifier for a customer in the US. He had a bunch of very specific requests for this build that started out as a reissue Fender. I designed two very different input channels based on his description and needs. The transformers were replaced with custom spec units as one of his requests was the desire to use ANY output tube from the little 6V6 through to big daddy KT88, hence the external bias test and set points on the back. The output stage was switchable from triode to pentode operation to further the flexibility of the output stage. This all posed some interesting challenges for transformer impedance and power ratings.

PSVANE tubes, are they good?

David, aka Grumpy, needs our help. Great news. David is home! It was quite the ordeal to get him home and into the house, but it is done. Thank you to everyone for their support.

The MC 70th Anniversary Vacuum Tube Amplifier is a Watt per channel stereo amplifier and features a striking new design to celebrate our seven decades of handcrafting some of the best home audio equipment the world has ever heard. Utilizing our patented Unity Coupled Circuit output transformer technology — the same technology the company was founded on in — the full Watts can be delivered to almost any pair of speakers regardless if they have 2, 4 or 8 Ohm impedance.

Totally Tubular: The Tube Thread

When you have enough knowledge to modify a given circuit you almost can design your own. I vote for blueglow though the circuit is unknown to me assume it is similar to Abdellah's kt88 se. Come on. Please be half serious and build something which will serve you for long time! Originally Posted by minhaj. There was someone on the AK forum that built the Blueglow amp with a 6SL7 driver tube and apparently it worked well.

Kt88 Se Amp

Ads are not permitted. My Firestone has push pull 6V6 , one does not glow, one does. I know that KT88's and 's will blue glow as normal. The Trouble with doing nothing, is that you can't tell when you're finished

Blue Glow — We often get asked if blue glow inside of a vacuum tube is a sign of a defect. Thankfully, it is rarely a sign of a defect at all. In fact, many tubes have a blue glow, especially modern tubes. Photo 1 shows a tube with a healthy blue glow. This was also seen in tubes from the golden age of vacuum tube production. Blue Glows are not tube detriments per se.

EL84 Exhibits many of the same characteristics as the EL34, but with a power output of roughly watts. Be sure and follow the resistor power ratings specified and allow for…. Now with the replaced V5 EL84 no hum all knobs facing noon, no input plugin connections , improvement noted as compared to the JJ's. Based on the Dirty channel of our Flagship Rockerverb amps, this ELpowered little monster pushes out everything from classic cleans to cutting-edge Metal, oozing character at every notch on its five simple dials.
