    Franken ST-70

    Post by MEDacko on Mon Jun 15, 2015 1:22 pm

    I have been dorking around for a while with tube amps, I have a few custom builds which I enjoy.  Last week my GF decided she wanted her own, without warning bought a modified ST-70 that required a bit of work.  I don't know who did the work or what they were trying to accomplish all I know is all four 330 V 800 mf  caps were blown up and 2 of the 150K 2W resistors on the left channel are toast. Under the chassis it appears to be signed by sombody named "Waddle" it's hard to read so I may not have that right.   I have no problem doing the work myself but before I dig in to it if anybody here knows of this configureation or has info on the mod I would greatly appreciate it.
