Re: #0150
Your Welcome.I do work on them from time to time.Along with two others which I never bothered to take pics of.All I vaguely know is,One was originally built for someone in Timbuk 3? and the other was for someone in Europe.Sweden,Norway?I do have more pics of these two.The current owner I will keep anonymous.All 4 of the amps are very different from each other as expected.#0130 has the values of some components written on them by Dumble.Some tubes are signed by him too!They all sound very good although not my cup 'o tea.

Re: #0150
Many thanks for sharing these! Really appreciate it! Also thanks for sharing the story
Re: #0150
thx for sharing! very interesting to see resistor composition, this one has the most darker sounding Piher in NFB..probably below goop is also carbon film, plus metal film for anodes.
here will be good to measure ratio and vol pots (100k=?) and output cupling caps in od section to these pots. some positive feedback in first and second stage, and also nfb wire is going together with anode in PI

#0150 appears to be a high plate Skyliner w/Music Man transformers likely built in 85 or 86. (deep switch functions as mid boost.) Btw. was this amp originally loaded with 34's?GTSjoe wrote: ↑Sat Jun 18, 2022 2:42 am Your Welcome.I do work on them from time to time.Along with two others which I never bothered to take pics of.All I vaguely know is,One was originally built for someone in Timbuk 3? and the other was for someone in Europe.Sweden,Norway?I do have more pics of these two.The current owner I will keep anonymous.All 4 of the amps are very different from each other as expected.#0130 has the values of some components written on them by Dumble.Some tubes are signed by him too!They all sound very good although not my cup 'o tea.
1w Piher's are fairly common resistor used in GNFB spot in 4th/5th generations including most gold script Music man amps I have seen. Here is another L.P.S w/MM iron.this one has the most darker sounding Piher in NFB.
Btw. Interesting to note 150 has no NFB around V1 so its sort of a 183 with Music Man transformers.

Re: #0150
Not uncommon, but IMO this would be near the end of the sn range for the use of these caps.
