tube amp

Let me explain. Monoprice sold a VERY popular “hybrid” tube amp for quite a few years. It was one of the first new pieces of equipment I ever purchased (I always bought second hand until then). At $100 or so on sale, it was an absurdly cool looking if somewhat questionable sounding 25wpc...

Hi Everyone, I have recently moved to Japan and wanted to put together a distinctly "Japanese" system. On the speakers side I am leaning towards the Yamaha NS-1000M. On the amp side, although I have been a solid state guy up until now, I have come across the Luxman MQ series tube amps and am...

Hey Everyone, I was wondering if ANYBODY would give me their opinion on painting my A224 Tube amp? I just picked up a beautifully clean and serviced A224 from my local repair shop however the black cover is scratched up quite a bit. I'd like to repaint it black. Maybe a silly question - but...

Looking for opinions on fair market value of a QUAD QC-II preamplifier and QUAD II monoblock amplifier in “unique” condition and obvious need of restoration. These are circa 1956 based on a QUAD Product Year/Serial Number Record form, posted at the Lenco turntable forum. The units were housed...

I did a search for this and although there is a lot of info on how to use the varias, there isn’t much in the way of what particular variac to use. BTW Not really sure if I even need a variac seeing as how both units have been powered up within the past month or so and were working properly...

I just got back from picking it up. The owner had his younger son there. A little arrogant guy with an obvious Napoleon issue lol. Settled above what we talked about as I guess the son did a little research. It’s fine. It’s mine and it appears to be in damn near mint condition. Have to manual...

I have a chance to grab this ST-70 but was curious what mod has been done. I’ve never seen one w 4 tubes on the board. Waiting for an answer from the seller. Says it sounds amazing, all new tubes and will demo. Any thoughts? Thanks! Bobby

I just got this sweet sounding 7b31 that has been completely rebuilt and am wondering what would be a good preamp to use that would pair nicely. Right now I'm just using preouts from my Onkyo A5, but would like something to complete this amp on its own. Open to ideas. Tube or SS. Only will be...

Good evening, I picked up this 175 in decent shape. Tubes are not the best but that will be corrected. I’ve been pouring over as many threads on this amp as I could find and therein lies a problem. There is so much info on AK I am a bit overwhelmed and confused about some things. Hoping I can...

Officially have the tube bug BAD! I have a chance to pick up this PHILCO console for nothing. Literally just have to go get it. I can’t make out the model number but my biggest question would be, is it stereo? Owner says it is but I’m having doubts. You don’t see a lot of threads on PHILCO amps...

Ive been poking around for a quality 10 or 15 watt tube power amp for a little while and not coming up with much. There are a few cheap ones on amazon, but I’m wondering why don’t any of the reputable audiophile builders seem to make a small wattage power tube amp? Any suggestions? (I...

hey guys! just signed up and this is my first post! so I just bought a McIntosh 275 amp and am wondering what it's worth. in great shape. only blemish is some of the letters have rubbed off where it says right channel. any input would be appreciated! cheers!

So, there’s a Rock-Ola 431 Jukebox available near me for a good price and I’m wondering if I can remove the 50 Watt Stereo Tube Amp & use it outside of the jukebox? I’m guessing I would have to remove the power supply and the Amp but would I be able to plug a preamp into it? There doesn’t appear...

I recently purchased a Scottkit LK 48 and I wanted to make sure I can use it with my Polk SDA 2A's. I am pretty sure I can but would there be any downfalls?

Hello, I recently purchased a Scottkit LK 48 and I wanted to make sure I can use it with my Polk SDA 2A's. I am pretty sure I can but would there be any downfalls? Thanks!

Hi All, This is my first AK post. Just wanted to share a recently completed project of mine: a homebuilt transistor-tube hybrid integrated stereo amplifier in the style of an early 1960's household hi-fi stereo set. The set was built as a modular system; with the exception of the power supply...

I’ve been at this a while and I think I’m happy with my set up. Went integrated tube with Rogue Cronus Magnum II. Upgraded to Telefunken 12AX7 tubes from the stock JJs. I’m very happy. Although my ears are old I was amazed at the improvement over my Rogue Metis preamp paired with an Adcom...

I’ve had this beautiful 72” wide Curtis Mathes The Royal Dane console for a awhile now but just got around to cleaning it up and plugging a CD player into the AUX. The sound is excellent and it’s one of the best looking consoles there is! I believe it’s a 1964 model. The cosmetic condition is...

Hello, As the title states, I wish to know which amplifier sounds better and why. I realise the Elekit is 8WPC while the ST70 is 40 however, either will work. Thank you in advance,

Hi, I got this pretty S81 in excellent condition and was planing to replace the filter cap. I bought and received this cap (500V 50uf + 50uf 85C New Can Eelectrolytic Capacitor for tube amp) and it mesear 54uf and 1.4ohm ESR. Out of curiosity, I checked the original (in circuit) and it measures...

Perhaps we can make this a sticky later on when the replies are condensed For me on my first acquisition 1. Cleaning ( my wife would not let the console in the house...not even in the garage. I sit outside in the sun for 3 days!) 2. Visual inspection ( for broken wires/connection, loose and...

Acquired this baby a few weeks ago and immediately started to clean out 50+ years of grime and dirt...the floor of inside the console had a few millimeters of yuck!

I'm a little hazy on this and the answer is probably self-evident. Question one: Which is more important to sound: A tube Pre Amp? or a Tube Amplifier? Question two: If the Amplifier is more important, can a SS pre amp feed into a tubed amp and will the results be similar or better? Or will...

Inherited a pair of old Wharfedale W70s (from ca. 1961) that have been refurbished. I was thinking of driving them with tubes but I’m wary of the hazards of a really old amp. Stumbled on the Jolida while searching around online, and I’m intrigued. Anyone have opinions on this amp, and/or on...

I'm interested in modernizing the tube chassis of my Allen 90's I'm open to various treatments and as I could not find any thread on this process I made one. Here is a photo of my amps. Please let me know if you have any positive thought to help with this project. Thank you. Marcos If you...
