■ガンズ/スラッシュモデルのアンプの不調修理■
信号チェック用のトランジスタアンプ、やっぱり気に入らない。というか、この個体アンプだけかもしれないけれどノイズ多いんですよね。
あと、ちょっとクリーンチャンネルとゲインチャンネルのスイッチ切り替えのノイズ(インピーダンス切り替えが適当な設計特有のボン!という切り替えノイズ)、とうとう我慢できず、数値だけとっておこうと思って再度分解。
(写真は前回の物の使い回しですが)
ノイズは徹底的にICの増幅帰還部にセラコンかなんかでパスコン入れるかなんかすれば収まるだろうとは思うけど、今日はそこまで追い込む時間はない。
後は切り替えスイッチは6ピンのスライド式なので、単にインピーダンス整合用の抵抗値を測定して割り出す。
ただ、手持ちに部品がない定数になっちゃったので、半固定でも突っ込むかと思った所でタイムアップ。
このアンプ、めっちゃデカい音出したら良い感じなんだろうけど、多分めっちゃノイズ多い。
スラッシュってこんなんでほんとにOK出したんやろかいな?
まーこの辺りは闇が有る世界なのであまり深入りしないでおこう。
蛇革(フェイクレザー)にでも貼り替えてみようかな。
SNAKEPITだけに。これは前も書いたか。
後、インプットジャック、これもちょっと勘弁してほしい。
初心者向けのコスト削減とは言うものの、壊れやすすぎるわ。
初心者物だからって言ってももうちょっとだけ良いの使ってくれないかな。
全体的に可愛らしいんだけどね。
でもしも結果真空管アンプに作り替えてたら、コンセプトからずれていく笑
(真空管アンプで信号チェックするのが暑いからという理由なのに)
あ、でもね、歪みはメッチャいい感じなんですよ。
チェック用トランジスタアンプだったらもうこれでいいかな。
あ、JCのちっこいのは欲しい。場所無いけど。

■ Guns/Slash model amp malfunction repaired ■
Transistor amp, I still don't like it. I mean, maybe it's just this unit's amp, but it has a lot of noise.
Also, the noise when switching between the clean channel and gain channel (the noise of switching impedance is peculiar to the proper design), I finally couldn't put up with it! ) I finally couldn't take it any longer, so I disassembled it again, just to keep the numbers (the photo shows the last one I turned).
(The photo is a reproduction of the last one.)
I think the noise will be fixed if I put a pass-controller or something in the amplification feedback section of the IC, but I don't have time to go into that much detail today.
The rest is just measuring and figuring out the impedance matching resistance, since the switching switch is a 6-pin sliding type.
However, I didn't have any parts on hand, so I thought I'd have to go in with a semi-fixed resistor, but then time ran out.
This amp would probably sound good if it were really loud, but it's probably very noisy.
I wonder if Slash really gave the OK for this kind of thing?
Well, this is a dark world, so let's not get too deep into it.
I might try to replace it with fake snakeskin leather.
Just for SNAKEPIT. I wrote about this before, didn't I?
And the input jack, please don't give me a break.
I know you say it's a cost-saving measure for beginners, but it's too fragile.
Even if it's a beginner's product, could you please use something a little better?
Overall, though, it's pretty.
And if they rebuild it into a tube amp as a result, it's going to be out of concept lol.
(even though it's just because it's hot to check the signal with a tube amp)
Oh, but you know, the distortion is really nice.
If it was a transistor amp for checking, I'd probably just use this one now.
I want a small JC amp. I don't have space for it.
