    Amp Building/Technical/Repair
    Hi, I play through a cranked Marshall Origin 20H with a G12 Greenback speaker. I was planning to replace the current EL34s with 6CA7s once they wear out. Is this a feasible option, or would I have to adjust the bias?

    NEW AMP DAY! I tried ignoring the local craigslist ad for this Sunn Solaris for 2 weeks, but the price was too good and nobody else was taking it. Both of those probably due to the fact that it was advertised as being in unconfirmable functional condition (” Fuse (and fuse casing) is blown...
