Excellent thanks Gordon!

Dave- would it be possible to briefly explain the self healing nature of film capacitors? Not something I’ve heard about before but I’d certainly be interested in learning exactly how that occurs.

The Electro Harmonix EL84’s may not live long in the SA-16. Even with the (somewhat) controlled warmup of the indirectly heated 6CA4 rectifiers, the power tubes see a spike of grid voltage in these amps on turn-on that will light up the screens long before the filaments have time to heat the...

Nice work on the Coronet so far. Looks great! The SA-16 has really been overlooked in Fishers’s canon and doesn’t get anywhere the love that it’s fixed bias brother the SA100 gets. It’s a very simple circuit but has great output transformers. Upgrading the caps to something better than the...

Thanks. I don’t think I’ve used a tape out since the early 90’s. I’d actually forgotten that my pre had one so when the thought hit me it was kind of a eureka moment. The integrated isn’t in my possession yet so I was just working through the set up in my head. My pre has output trim pots so my...

Hey all- I have decided to give a DHT SET amp a try. I did quite a bit of shopping and because I have a full function tube pre that I’m very happy with and is quite flexible gain wise, I was looking for a basic amp. What I found that suited me power and price wise was a Bottlehead Stereomore...

Earlier Dynaco silk screened tubes like Dutch Phillips and Mullard had a larger Dynaco screen on them as well. I’ve even seen some with a vertical orientation of the text. Those would have shipped with Mark II monos and would have probably not have been found in a quantity of four tubes as...

Almost certainly Tesla Roznov from late 60's to mid 70's, made in Czechoslovakia. The precursor to today's JJ Tubes. Giveaways are thus: looks like a Phillips Netherlands or Belgium made tube, reddish brown bakelite base and spot welded plates but lacks that tubes distinctive double D getters...

I'd like to thank everyone that responded and I apologize for disappearing for so long. I'm in the process of opening a new restaurant and it's consuming the majority of my time. Interestingly enough I've determined that Im using in the neighborhood of 1 to at the most 2 watts for the majority...

Thanks Bingo! I’ll give it a go! Exactly what I was looking for.

Ok, I already know this is a tough order but I’m going to try anyway. I’m planning a purchase of a single ended DHT amp or monos. I’m undecided on whether the power output of 2a3 or similar triode will get me the kind of power for my desired listening level, or whether the increased power of a...

I have used the L shaped brass adapters on my SA-16 for years and have never had an issue. They hold firm, don't sag and to my ear are acoustically transparent. I also hack sawed a pair to fit cleanly on a Bogen AP-30 integrated amp with great success. I wouldn't worry too much about them as...

Any chance that Genelex U77 has a Blackburn `B` code on the glass? I saw one listed in an epay ad once and was clearly a relabled Mullard which while it certainly wasn't a bad thing, showed some outsourcing took place at Genelex too. Come to think of it I've also seen Mullard labeled KT66's and...

My parents always had music playing when I was a kid. My father was a die hard Pioneer receiver guy (we're talking 70's here). At some point after my parents divorce my new step father came home with a brand new Fisher boom box, a huge one, silver with detachable speakers and a phono stage...

I have been off the forums for nearly a year and only recently came back to AK and other forums. This morning I stumbled on to mention of Kegger's passing on Bob Latinos Dynaco forum and came running over here. I'm very saddened to hear of this terrible news. Kegger was a resident expert on...

Gadget- You're correct of course! My other one is the changer and is in fact an A II. The one in the console is an AT6 as you noted. Good eye, my error on that . I had assumed that they were both considered As because of the prefix. Thanks for the correction .

Thanks guys! And to Rob, no hijack possible here. I just wanted to show this console off as I finally got the 400 that I purchased for it like 8 years ago installed yesterday..Fisher manufactured consoles get a lot of love on AK and I'm a big fan of them as well but this one seems to be pretty...

While I'm here some pix of my main (Fisher based) rig. AR XA turntable, VTA SP-12 preamp driving either the Fisher SA-16 or AES AE25 in triode to Zu Omens. Bogen tuner and integrated at bottom belonged to my wife's grandfather (also North Jersey, Bogenland?). They both contain all original...

Also I forgot to mention the speakers are 8" with whizzer cones and are front ported. The cabinets are lined with fiber glass. There's enough room on the motor boards to go to 10" and enough internal area for more magnet structure so that a coaxial or something similar could easily fit. Could be...

This console belonged to my grandfather. He purchased it in the early 60's from an unknown source in North Jersey. I'm not sure if he had it custom built or bought from a furniture store. It's a teak veneer over very high quality furniture grade hardwood ply. Original electronics were a Bogen...

Yes, I have used a Niles DPS-1 in situations like this with much success. It's an A/B switching box that can be used either with one amp and two sets of speakers OR with one set of speakers and switching between two amps. I've used it both ways. It's important to note that most tube amps should...

Oh this is funny! I'd never seen these threads: http://audiokarma.org/forums/index.php?threads/another-fisher-score.317533/#post-3934755 http://audiokarma.org/forums/index.php?threads/my-finished-sa-16.318265/ This is my amp! Looks like another AK'er recapped it 2010. I'm still using the same...

From my experience Fisher shipped these with 7189's installed. The ones you mention may be Raytheon manufacture as to the best of my knowledge Rayovac was and is still primarily a maker of batteries. Raytheon did however make excellent 7189 tubes. Unless your amp has been extensively modified...

I have an SA-16 that I bought on EBay about 5-6 years ago. I was looking for a basic EL84 amp with nice output transformers and tube rectifier to recap myself. I ended up paying $300 and change for one that had already been nicely recapped by the person whom the EBay seller had bought it from...

Hi repair_guy, any chance of a picture of the upper chassis and tube layout on this receiver?
