kt88

So here we go, Guy purchases my cherished MC275 amp with OG Mcintosh KT88's and 12ax7/12aT7's and all have been babied and were never left on for long periods(meaning days). the getters are nice and silver/mirrored and the amp sounded amazing. Two weeks after selling, i get a text, "the amp...

Hello everyone! Thank you for letting me in. I would like to showcase my latest mini 6.5W SET amp that I am loving it very much:jump: I am still learning and figuring how to improve it bit by bit everyday. :beerchug: .

Hey everyone, I'm in the process of picking up a Scott LK-150 but unfortunately it has no tubes. I was wondering if anyone here has tried KT120 tubes on this amp or of they draw too much current to be safely used here. When it gets here this piece is going to need a decent amount of work before...

Hello Everyone, My first Post. My Name is Randy and i have built quiet a few Amps so far. (All KT88 SE and one 6L6 PP) Im currently working on a KT150 SE Project and unfortunately already to late i figured that i might have the wrong OT? In the schematic is a Hammond 1628SEA which is a 5k OT...

I was hoping that someone that owns one of these could comment on whether it uses a circuit board or if it is point to point wired. The description of the MT-88 says: Hand welding point to point. Features: Handmade scaffolding welding, there is concise and easy process, traces short, simple...

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...

will report back when I plug it into my system. It will eventually be powering Fyne F500 set of speakers.

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...

Hello. Built this long time ago The thing is I get only 2.7Wpc- 2.8Wpc. It also has what I believe its a big THD. Didnt measure but saw it in the FFT of the scope. How many watts do you get in your builds of this amp? Btw I added some mods according to Kegger suggestions in that time. 220R an...

Anyone using the Luxman mq-88uc? I am testing the Luxman mq-88uc with the PMC Gold db1 apeakers. sources are: Luxman d-n10 cd player connected via coaxial to a mhdt ATLANTIS DAC A&K300 player connected optically to the mhdt ATLANTIS DAC Belcanto DAC 1 same connections as above Luxman d-n10 cd...

Hello everybody, a while ago the hifi passion revamped, I took dust off the JBL4311B and reconnected the old Adcom GFP345 and GFA535, visiting a friend's place I laid my eyes on some of the gear from his gone dad he wanted to sell and I got a marvellous Gyrodec TT and an Audio Research SP9...

Hi All, this is my first thread on AK :banana: I am constructing an amplifier that is inspired by the Mullard 5-20 amplifier. Changes to the original design are: EF37 input pentode, 6SN7 phase inverter/driver and KT88 output tubes. Has anybody attempted something like this? :beatnik:

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...

Happy new year everyone! I've been really busy but have wanted to build the Kegger se kt88 for awhile now and after seeing blueglows youtube videos I'm sold. I enjoy my 5 watt se builds but have a party coming up this spring and need more power so am ready to get started but have a few...

I just upgraded the tubes in my MC275 MKVI from the standard McIntosh tubes to Shuguang Treasure KT88-Z black bottle tubes. I notice that the Shuguang tubes run a lot hotter than the McIntosh tubes. Have other people noticed the same?

McIntosh 40 MC40 Can I use KT88 or 6550? Does anyone know the current capability of the filament winding of the power transformer? Thanks

I kind of described my system in the introduction thread on the dedicated forum, now let's switch to sound expectations. The oldest piece in my system is the couple of JBL4311B which I bought in my teen age, they are over 30 years old and still sounding, not just sounding, even the pads still...

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...

Dear McIntosh experts. I have had used my MC275 MKV for 1½ years and love it. Some time ago the fuse blew. I replaced it and the amplifier was working and sounding fine afterwards. But I noticed, that one of the (original) KT88 tubes (V11) was not having a purple glow in the surface of it...

Hello friends... I came upon a pile of used KT90 and used Svetlana 6550C ( I don't know how to figure out if it is winged or not. 16 of KT90s dont have any marking and other 16 have Ei VTL in blue lettering. Guy who sold me said the amp he was using used these some 20 + years back and he...

Hello Gentleman. Now that I've trolled around for years and stolen all of the fantastic information that you selflessly post, I promise to start contributing more now that I have learned enough where I actually have something to contribute. Today, I'm hoping to get some tube advice from the...

Here's a photo of my new Quicksilver KT88 monoblock set.
