tube

First, I'm new here, and inexperienced with vintage/tube audio. So, if this should go somewhere else, let me know. I inherited a Motorola sk28w "Stereophonic High Fidelity" console a few years ago. Since then, it's been used for setting things on. It had been a couple of decades since anyone...

HELP! I recently did some work on my Fisher X-202 upon turning it back on, it started playing, but it sounded odd and I heard a lot of general distortion (at least in the R speaker, which I was sitting beside)... then I noticed one of the four output tubes was glowing BRIGHT RED, so I...

Have you come across parts or devices released in the USSR? What did you use them for?

@dusty-rhodes sold me a very nice we369a getter tube for my DAC. Paid via PayPal and received the tube a few days later, packed in THREE LAYERS of bubble wrap and a sturdy double box. Nothing but a bomb could’ve damaged it.

Hope some of you Fisher guys can help me with this Fisher 400 I payed good money for off of the bay, been wanting one for years so I'm hoping this one turns out nice. So since I have a chance to return this I have been doing some basic checks. So far I have only been able to get a few clean...

First up is the Sovtek shirt from the 1990,s Tube on shirt glows in the dark. Next up is my MFSL shirt I think from the late 70,s or early 80,s, I had more then one of these but this all I have now. Enjoy

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...

Alright I've posted threads before looking for some insight on what I should upgrade to but ultimately at that time I didn't have the money saved to really take anything seriously. many hrs of overtime later I've saved up some cash for something new (restoring vintage gear isn't cheap either). I...

When I first bought my Realistic SAF-40D integrated amp , I had thought maybe Trio-Kenwood had built my amp after looking through threads on here and other sites. Although Radio Shack kept their amp supplier a mystery, some compared the amp's topology to that of contemporary Kenwood amps. But...

I'm interested in building a tube amp kit but finding good information is quite a slog, since mentions of the various kits are scattered across many threads, and there's no way of knowing when you've discovered all the kits that are out there. I strongly prefer to compare every possible option...

Does anybody have any idea what my all original opus 5550MX and RB45 might be worth?

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...

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...

These came out of a early Sony R to R. Hard to find, as a retired tube dealer I have never seen more then a handful of these. Sockets in the r to r were marked 12AD7/ 12AX7

Hi! Is anyone using a tube amplifier with the PMC db1 speakers? I have been using the db1 Gold with the Rega Brio (2017) and a Belcanto DAC 1 for 2+ years now. I only use CD as a source - a Luxman D-N10. I find this system very good and balanced, plays all tyles of music quite well but I have...

Hi, I'm trying to bring a pair of MB3045 back to life. They are both equiped with Sovtek 6550 wich I will replace by NOS Sylvania. I found a few mods inside, and they seem to differ from what I read: - Around the 3x47µF/450V capacitor, I see 12K-68K-150K instead of 12K-100R-150K in the original...

Over the weekend, I picked up another QSC USA 900. I like my current one, the price was right, and a backup is always good. While I was there, I helped the seller get rid of more stuff, as he was cleaning out his garage. I'm now the new owner of a couple Pioneer tube receivers, an SAE...

Hey folks! Is anyone out there using the new Schiit Freya+ preamp? Just wondering what people think of theirs as far as sound quality. I know not many are in circulation yet, but thought I’d ask. I’m presently using their original Saga passive pre and while it sounds clear and clean, I want...

See pictures this cabinet was very rough, now wow. I have placed my lesser of my two 500-C in this cabinet. This will become the heart of my " Bedroom System" that I have not setup yet.

Hello, I recently purchased a used McIntosh MC275 IV amp, and upon hooking it up I noticed distortion on one channel right away, seems to get louder as the volume goes up. The whole unit is not as clear or as good as i expected it to be. I have swapped the original McIntosh KT88 tubes and the...

Hey everyone, hope everyone is staying cool this July. Just ordered an Eico Hf-81 and was wondering is anyones noticed that there seems to be two versions of the output transformers, anyone know if there is a quality difference? Also any idea of new pots to replace the old tone controls? Really...

I was browsing in Facebook this evening and found this beauty in Mississippi Mills! The price is quite reasonable however this would be a mono system. Anyone know what it is? No affiliation in any way. I just thought it is really cool and had to share!

Hey all, Still new to this world, so thank you in advance for any insight. I have a Scott 299B with some later production KLH 6s. It’s incredible. I would love to be able to use headphones, mostly for night use. I saw this article...

Hey guys really need some help. So my vtv dual triode characterizer gain meter needle is toast. My tech friend tested the continuity and there isn't any. Am I just sol? If anyone has advice on what the heck I can do ie If a replacement meter may still exist somewhere or if you have a dead vtv...
