Post by Nick » Thu Sep 08, am Thats fine, but if they are posted as attachments, then the forum will display them as a smaller image to click on to see the full size. It was a problem before when folk posted entire images, the page width got huge and so a problem for folks monitors.
I would need 2 x power transformer, rectifier tubes, diodes, etc, however, it otherwise seems doable. I'm debating about whether to have nice chassis' made which I've done in the past or just something I already have access too that would fit the utilitarian needs but won't win any design contests.
I do tend to like a sharp looking amp however. Also, I don't see at sp wound components link below where there is a mains tx that fits the requirement of the schematic. Anyone have a specific reference number. I also thought if I went with monoblocks I might just have a high quality pair wound here in the states like with Electraprint. This is something that Michael percy substituted either to save me money or he did not have the V-Cap.
If you guys think that I really should go with the V-Cap it is not a problem at all. At this stage a few more dollars is a moot issue. The cost for these is relative cheap compared to the V-Cap. They still use interstage transformer as phase splitter. In some ways they could be viewed as an evolution of the WAD design. Post by heli » Thu Sep 08, pm Greg, Thanks for the reply and I will post the resistors tomorrow.
Did you see anything else in the picture that raised any concerns? The C-8 capacitors are poly film, tiny and Green, see picture below The trannies are intown and will be delivered tomorrow. Getting close! You do not have the required permissions to view the files attached to this post.
It is hard to get upset with someone if it takes their complete brain power to keep themselves breathing. Your component selection looks good to me. Having said that, one of our original clone conspirators Steve Grimshaw had an overall dislike of electrolytic caps and built the whole amp using polyprops and it sounded very good.
It doesn't need to be too prescriptive. You can suck and see and return later with changes to see if it improves your sound. That's all part of the fun. Those caps for C8 will be fine. It's not a big deal and probably you won't need the feedback loop anyway. I've not yet found anyone who has needed to use it and after listening tests I found it completely unnecessary.
I hope that helps, Greg. I have included a picture below Anyway, the Black gates you used were they FK or what series? Thanks, W. I don't think the value was available in FK, otherwise that would have been my choice. Post by heli » Thu Sep 08, pm Greg, I understand the feedback loop and not using it. Before I really start serious wiring I want to check with you guys to be totally sure that I am using the latest updates. Hopefully THIS build will have everything incorporated into it and will save someone from having to do all the leg work involved.
I really appreciate the feedback as it helps me figure out all of the great information that you and Jan and a few others have offered. Everyone's input is VERY valuable to me so please keep it coming.
If there is something that all of us need to discuss and possibly change something, I hope that we can do it here and get a better amp for our trouble! Post by heli » Thu Sep 08, pm Greg, You had Black Gate on your material list and I could not find one in a volt range, hence the substitution. I hope this German cap will do the job. The problem is that Blackgate's stopped being produced a couple of years ago, so what you can now access is outstanding stock.
Until recently, M Percy had the greatest choice and I took advantage of that and ordered in some spares. Looking at his catalogue, it now seems his stocks are seriously depleated and of course will eventually run out. We will all now need to find alternatives. Many mourn the demise of the Blackgate and actually can't really understand why production stopped. I suspect it was because the commercial market found them too expensive and the DIY market was way too small.
I'm sure the German job will be just fine. Post by heli » Thu Sep 08, pm You hit it Greg Everything I have read about the demise of Black Gate supports what you have said. It is a shame as it would be nice to have used all Black Gate but i am sure that there are other capacitors that are as good in sound quality.
When I had to substitute, I tried to do the research to get as good or better replacement but I had to depend on what I read and that is why I value the opinions from people that regularly build amps.
You get to a point of where the cost totally deminishes the return as it is hard to justify for a cap that can be bought for 20 as it raises the question of how much better is the sound from the dollar cap? If money is absolutely NO object then I guess the rich person can justify the expense. They make caps that cost more than the truck I drive!
Post by Ali Tait » Thu Sep 08, pm Not that I know anyfin, but I'd just build the amp with what you have and run it for a month or two to let it run in and get a handle on how it sounds. You then have a baseline against which to try tweaking with different components.
Post by heli » Thu Sep 08, pm Ali, I totally agree with you. I feel pretty confident about the substitutions that were made but things like the little Green things above do trouble me. It is nice to know that it will NOT be used. When I ordered parts, I just ordered what was on the master list and made substitutions where necessary. I am relying on you guys for any changes that need to be made befpre I start soldering.
Audio Note 300b Amplifier
Hi all, First-time poster here hoping for some guidance. I've done a search on my issue and thought I had it figured out, but alas About 4 months ago, I noticed that half of the filament on the right channel power tub was out. They were Electro-Harmonix Bs, about 10 years old, probably in the 12,, hour range, so I figured the tube had just died. Replaced the tubes. Then within a couple months, the same thing happened on a brand new tube.

ANK 300B Interstage Monoblocks
The circuit is fully dual mono on a single chassis, with dual 5U4GB rectifiers and two massive power transformers and chokes. Internal components have been upgraded to better quality components such as BC capacitor for power supply, Nichicon Fine Gold for cathode bypass, Dale Resistors and Russian oil capacitor K75 green military for coupling. Features: Preamplifier use SRPP amplification circuit and Nagao-type inverter circuit, make it let the audio frequency wide, distortion is little. I am including a fresh new set of Soviet 2A3 output tubes along with the originals. The audio path is completely free of Class AB switching artifacts, Class D high-frequency noise of transitions between output pairs of devices.

I believe that you are wrong. I'm sure. Let's discuss.
This is a very valuable thing
In my opinion, this is an interesting question, I will take part in the discussion. Together we can come to the right answer.
