差動回路で構成した優等生には出せない味がある

ぺるけさんとこの「トランジスタ式ミニワッターpart2」です 前回、正負両電源の19V版（最終版）を作ったというのに、初期型の単電源仕様のpart2を作るのは本来なら有り得ない事です 逆行も甚だしいこの流れは、変態の愚行と言わざるを得ないことです

but　探求心と好奇心には逆らえない

先に、感想を書きますと この12V単電源仕様のOTLアンプは　とてもいい音がします　僕はこの音の感じ　すきですね 差動回路で構成した優等生には　出せない味がある 回路は簡単だし、FETの選別に悩まなくていいし、省エネ

Gorgeous Accuphase P-360 Power Amplifier Overhaul

Oh yes, and this one is also for sale! Welcome once again folks to the fourth article in nearly as many days. This time we’re looking at the overhaul of my gorgeous Accuphase P-360 power amplifier and what must be my last post in this seven-day posting epic. Writing these articles is involved and time-consuming but very rewarding. I’d forgotten how much I love to write once I get on a roll. As…

What are the differences between Class A, AB, and Class D amplifiers?

オーディオアンプは数字では評価できない

真空管に5687を使用し、出力トランスに東栄変成器の廉価なT-1200を使用した時の特性です。T-1200は高域側の帯域があまり広くありませんが、ピークポイントでも位相特性は非常に安定しており、��域側はこのサイズとしては申し分なく、価格も含めてバランスのとれたいい出力トランスだと思います。中身はイチカワのITS-2.5Wと同じです。

歪率特性はシングルアンプそのもので、右上がりの一直線ですので、歪み成分の大半が２次高調波であることが読み取れます。最大出力付近のくぼみはA2級動作の特徴です。1kHz、5%歪みで0.7Wですが、歪を7%まで許容すれば100Hzでも0.7Wを得ています。これがT-600になると100Hzでは0.22W（7%）までダウンし、ひとまわり大きいT-850では0.1W（7%）を出すのがやっとという事態になります。ミニワッターとしてはT-1200のサイズがボーダーラインだといえるでしょう。T-1200未満のサイズの出力トランスはど��ブランド、どのコア材をもってしても低域特性の陰りを克服できたものはありません。

スペック的にとても低歪とはいえないアンプですが、これでいい音で鳴ります。（中略）オーディオアンプは数字では評価できないといわれるゆえんです。

using the ol' 9 panel grid for dave sadek's timeline! so he might have been experimented on at some point and came back kinda weird BUT he's still in one piece so it's all good 👍

GET IN KIDS, WE'RE WRITING YOUR REPS

Pretty much all of us aren't going to be able to immigrate. Canada's not doing great right now anyway (sorry guys). Legally your best bet is to get your state government to protect you and yours. Why? Because the MAGA Republicans are apeshit about states' rights, so might as well use that against them. If you live in a Blue state, now is a good time to write to your state-level reps about safe haven laws for LGBTQIA people and immigrants and safeguarding steps for reproductive health access.

The past few days, a handful of governors like JB Pritzker of Illinois and Maura Healey of Massachusetts have made bold statements about protecting their constituents. California has called a special assembly to try and hammer these safeguards into law.

I'd recommend writing to your reps and the heads of your state's Democratic party in the legislature about following their example. I know I'll be writing to CT Majority Leader Bob Duff, as he and his staff have been very sympathetic about trans rights in the past. The trans community's eye in the sky, Erin Reed, wrote an article about the CA special session and what's legally possible for a legislature to do to covers its figurative ass. Look up your reps! You've got federal, state, and local ones! Are your reps pieces of shit? Write to other reps. I wrote to Bob Duff before I was even a resident of his state. He STILL isn't my rep, but he's the Majority Leader and that's still plenty of influence in a Blue State.

PAM8610 class D Power Amplifier (modified)

2024/09/01　この基板はゲインが+32dB（最大）に固定されているので、-20dBのBass Boost付アッテネータを前置した。大幅に利得が落ちてしまったが小型スピーカでも低音がいい感じで出ている。思えば遠くへ来たもんだ。PAM8610は評価（世評）の低いICだが、ここまで来ればもうこっちのものだ。

　AMラジオを近づけてみると、２０ｃｍ以上離せば影響（雑音）は許容レベルである。発する雑音の大きさ（強さ）は　Zobel Network ≫　アンプ基板　である。
