6v6

What? My last post was 16 years, 1 masters degree and 2 kids ago?!? Well, I made the mistake of picking up a soldering iron, smelled the fumes, and now I have some Edcor transformers and a giant box of parts on the way to my home. I looked at a couple of PP schematics and of course couldn't find...

Hello Audiokarma! I'm restoring a Viking (department store brand) mono tube console from 1956. Its a decent quality unit claiming "High Fidelity" with a push-pull 6V6 output stage and separate filament supply for the preamp. I replaced all the electrolytic and wax capacitors and then connected...

I've never come accross this before. I didn't think it was even physically possible, considering the there should always be a voltage drop across the OT. I'm restoring a pair of V-M model 165s for a friend. After replacing all the old carbon comp resistors with modern metal film resistors of...

Manifesto SE ... a single ended tube amplifier project by HB. The physical layout is breadboard-minded, with exposed signal circuits connected to the power supply via umbilical connectors. The power supply is a LOW DCR "flywheel" type with 250VA Hammond ICT as the main B+ transformer. The...

It's been awhile since I've posted... Anyhow, I'm about to start a rebuild on a 185AA. I've just completed an 8802 that turned out well, but other than changing the value of the cathode bias resistor and a few cap values, I made no changes to the topology at all. With this 185AA, I'd like to...

Hello everyone. I'd just like to hear everybodies opinions on this topic. I have two acoustat woofers that will be subs for my room (I like a little extra bass personally), a 5 watt 6v6, and a pair of optimus 5bs I'd like to econowave. Id also like to invest in active crossovers to facilitate...

Starting on this little DuKane amp I got last summer. I began with the power cord which was roached. I thought it a good idea to go with a heavy grounded three prong plug. However I read somewhere that’s a bad idea in this case due to the way the microphone Is supposed to work. Not sure I’ll use...

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...

I'm on the lookout for console amp project. I would like to know what audiokarmians would consider some of the best common 6v6 console amps that can still be found in the wild for little monies? Are there other amps I should consider as well? Maybe some others with more output power? Thanks

The shop amp is back on the bench for repairs after an event during use which was a loud pop followed by red plating of a finals tube. The amp was shut down and the tube replaced but to no avail. There was nothing more to be heard from it. I focus my troubleshooting with a visual...

Finally found a Magnavox stereo console in my area, paid more then I should have but it fit in the back of my car and worked to a point and had the stereo mpx decoder deal, turn table might be shot but haven't ruled it out and I have a backup in nice condition so may finally have a fully working...

Hello, Another post seeking help wiring a nondescript Dynaco tube board from Ebay. This one is a Dynaco 6v6 ultra linear circuit. I have the power supply issue under control, but I'm looking for advice on how to properly wire the output transformers to the board. I've read that the OPT for...

Hey guys. I recently picked up a nice old Magnavox 8802. Well, I think it is an 8802, but when I google 8802, mine seems different from most I come across. I have two 12ax7's, a 7025 for Phono, four 6v6's, and a 5u4gb rectifier. 4 trannies, so I have the choke. I want to get started recapping...

Hello everyone, I hope this post finds you well. This might get lengthy and I still won't hit every point I wanted, but here's an initial writeup. Feel free to skip and look at the pictures/schematic that I have attached. Earlier this year I decided it was time for another electronics...

I have a great sounding and looking little rebuilt Magnavox 8802 that really is limited by the output transformers, I also have an old pair of 30w PP transformers laying around, so I think to myself project time. I just don't know which load would be the better option. RCA says 10k for 6V6 pp...

My next project is a Stewart-Warner 72CR26, a post-War (1947, I believe) AM/SW receiver with turntable. I picked it up from an estate-sale-hopping friend for $40, and plan to restore it and sell it to another friend for cost to put into her kids clothing shop (she's a big Giants fan, so hey...

Having cleared a couple of projects off the bench, of course it's time to start a new one. As you may recall, I built a Magnavox 8802 clone for my daughter last year for Christmas... I was planning to do the same for my son this year -- holy cow if the stuff isn't THE SAME, sometimes you sure...

I know this isn't hi-fi, but it is tube... hope I'm not breaking any forum rules... This is a project that I've been meaning to finish up for quite some time... I built it last spring (2015) and have been using it practically every day since then, but I finally made the final tweak to it, so I...

The following videos document the repair of this model of a Danelectro amplifier which has no known schematic available which presented an extra challenge. Video 1 of 3 Video 2 of 3 Video 3 of 3

Here is a video I made documenting a repair I did on the 59 Gibsonette using some extra care to keep the components looking as stock as possible. This one was plugged in when it should not have been so every thing needed to be tested after a complete burn out. The restoration movie The...

Picked up another Magnavox 8802 for a song with the intent of more heavily modifying it. It included what appear to be the original tubes, but I've never encountered gold-topped tubes before. This seems to be some sort of coating painted on the outside of the glass and pretty much exactly...

Hey everyone, Im working on a 1959 gibsonette and I have tested the audio output transformer which matches the exact ratio as listed in the technical literature which is 27.5:1 The finals for this AMP are dual 6V6 running parallel single ended into the transformer in class A The speaker...

I have this old Sears Silvertone 528.59441 console amp, from a Sears Silvertone model 70A console (AM/FM tuner, turntable, tape input, 1 external speaker for stereo). It was the listening device in my office for a spell, but was replaced by my Magnavox 8802, at which time the Silvertone took up...

Hello All, New guy here, just got a V-M model 915 that appears to be in pretty good condition. I like old stuff, particularly well made stuff made in America and I'd like to get this thing going and then refinish the veneer. Console by Sam08861 posted Jan 16, 2016 at 9:27 PM Model Sticker by...

While I'm waiting for parts for my console project, I'm trying to get my Voice of Music 6V6 fired up. It has odd, to me, speaker terminals and I'm not sure how to hook things up. It didn't come with speakers or speaker cables. Here is a copy of the schematic. I'll upload some pics shortly...
