Conversion to TS808 - this seems to be a perennial hot one. Simple... just locate the 470 ohm and 100k resistors on the output buffer transistor, tracing back from the output jack, and replace them with a 100 ohm and a 10K. Bang, instant 808. If you're doing this to a TS 10, short out the 1K resistor leading to pin 3 of the dual opamp as well. A variation of this mod is to add more bass response as in the next mod. This is sometimes referred to as making it have a "browner" sound. More bass - remember that 4.7K/0.047uF network on the (-) input of the clipping amp? To give yourself more bass, increase that cap to about 0.1uF. The (-) input is pin 2. More distortion - everybody's favorite. No problem here. If you want more distortion, lower that 4.7K to get more gain when the drive control is maxxed out. If you don't also want to change the bass/treble response, you will need to change the capacitor as well. If you half the resistor, double the capacitor to keep the same overall frequency response. It is theoretically possible to just use a higher value pot in the drive control, but you're unlikely to find a replacement for the micro-sized pots used in the original case. This is a possibility if you rip the circuit board out of the original box and install it in another box of your own choosing. This is not as crazy as it sounds, especially for the potato-bug TS5 as the plastic case is essentially useless no matter how good the circuit sounds. This leaves room for a true bypass switch as well. Note that if you take the step to go to a box that lets you use different pots, you can also add switches for other functions like changing the bass response by switching in another capacitor, switching in other gain resistors or pots for various degrees of gain, or other tone control pots for changing the treble response. Note that in going to higher gains, you will inevitably increase the noise in the output. This may be curable to a degree by changing the input transistor to a quieter part (MPSA18 or 2N5089 is good) as well as swapping to a more modern and quieter opamp like the LM833 or both. Sweeter distortion - the stock units use a pair of silicon signal diodes, which look identical to the 1N914/1N4148 devices. If you change one of these diodes, chances are that the resulting pair will not clip at the same voltage for positive and negative signals, giving you asymetrical clipping, and the resulting even order distortion. If you pick something close, like maybe a silicon power diode like the 1N400x series for the second diode, the resulting second harmonic will be very subtle, not audible as an octave effect at all, just a "sweeter" or more liquid tone. You can try a number of things like putting one germanium (1N34A from Radio Shack works) diode in series with one of the silicons to add a bit more threshold voltage to one side. A more radical treatment would replace one of the silicons with three germaniums; even more radical would replace one of the silicons with TWO silicons. These last will start to make an octave effect just barely audible at some notes on the guitar neck. I've even heard of using LED's in there for the clipping diodes. Go wild here.
基本上你也不用這麼麻煩，買一棵TS-7就解決大半問題。因為TS-7用跟808一樣的JRC-4558，所以你自己不用拔IC，而且TS-7很便宜Tone也比TS-9RI好。目前在國外的討論區上TS-7評價都比TS-9RI要高很多 C
1998年(正確時間有點忘了)TS9RI第一次出現在台灣,當時TS9DX也出來了,所以剛好可以做比較,我當時是選擇了TS9RI,原因有三: 1."太經典了(名稱)" 2."TONE比DX來的溫阮 顆粒園" 3."便宜$200"基於這些理由,當然選擇TS9RI. 往後確實個人還是比較喜歡TS9RI..... 200x-IBANEZ出了一系列TS,當然有TS7,所以也是玩看看摟,不過 我聽覺能力也是會慢慢進步,也非當時年輕的想法了 我無法說明當時我對TS7的感覺,只有便宜(一分錢一分貨),我立刻將他拔掉,也忘了他.... 2004-2005 這時 出現了maxon 製造的ts9 及 OD808相當不錯 前者TURE BYPASS 非常乾淨有利, 後者輕巧價錢合理也不錯 ,可惜 當時的我只喜歡音箱TONE所以不迷效果器.....只到出現TS808 RI我立刻就買了(當時在台只進六科,台南全吃)我連試都沒有就買了 原因有2: 1."它的名氣更勝之前" 2."TONE果然扎實 有利 帶點溫阮(讚)", 把MAXON的OD808打的死死的(剛好朋友哪來比...可憐阿) 以上純個人心得感想 沒有對錯好壞......

2001的文章......ali現在是不是還在這邊這還是未知數....... 就我拆機的經驗我可以回答你"是" 應該說 TS-7是用JRC-4558系列晶片 TS-808也是用JRC-4558系列 TS-9是用其他的(我忘了型號,數字一堆)
