    Restore Marantz 2226B

    I reveived this Marantz 2226B for a good deal. I have decent enough experience soldering to PCB(making keyboards) so I think I could do a recap. I realize no one is going to hold my hand through the entire process but, I am quite lost when it comes to what brands/types to use for what and where...

    JBL LX55 Restoration

    I’m just now getting to work on a pair of JBL LX55 speakers I picked up from goodwill a few weeks back for a whopping $4.99 each. I knew nothing really about them at the time but operated on the assumption that all JBL speakers are worth at least $10. Cabinets are a walnut VINYL veneer...

    Original Large Advent Restoration

    About one month ago I picked up a pair of original large advents for $10 (these are the walnut veneer ones with beveled front edge). Before you praise me too much on this deal, only 1 is a complete cabinet. The other cabinet is missing both drivers and beige grill cover but at least has the...

    Basic recap and restore BOM parts list on Kenwood KA-4002 integrated amp

    Performed a recap and basic restoration on a small Kenwood integrated amp KA-4002 and it sounds great. The KA-4002 has a cap-coupled output, so it has a warm sound kinda like tube gear and very much so the "1970's vintage sound". All electrolytic caps and "noisy" small signal transistors...

    Widening modern trimpots or trimmer resistors to fit 7.5mm PCB holes

    I'm replacing the trimpots in a vintage (1970's) receiver and I've ordered standard Bourns trimmer resistors, but the new pots have 5mm lead spacing whereas the old ones have 7mm or 7.5mm, so the PCB has the wider-spaced holes. What is the best way to deal with this cleanly and reliably? 1. I...

    Marantz 2220B 'LOUD' popping noise!

To be fair, it has NOT been restored but I cleaned the pots pretty good. Not sure what this could...
