  • Need Bedrock Royale Reverb build help!!

    (Newbie here. Pardon my ignorance if I don't post correctly - I will learn!!)

    Does anyone have a proper schematic, layout or even a picture of the Bedrock Royale Reverb circuit board??!

    I bought a Chassis and Tranny on Ebay from one of you guys here on the Forum a few years ago. It has sat on the back of the project pile forever and I want to get it finished. If I remember correctly it sat on the sellers pile for a few years before the sale too!!

    These were supposed to be pretty cool sounding amps and a fairly unique circuit due to the PI. Basically a Matchless Clubman or Chieftain Reverb but with that unique PI. I play harp and guitar and this PI is G. Webers preferred type used on his Roughneck amps I think.

    I have the pieces to the schematic from the Bedrock site:

    http://bedrock27.tripod.com/bedrockamp/id4.html

    As you see they are almost like notes and kind of unfinsihed.

    I will try to attach my extremely crude hand scribbled layout for anyones advice, feed back etc. I am not a tech or well versed technically but I do a lot of repairs and have built and modded many amps over the last several years - most with help from folks like yourselfs and AX84, 18 Watt, Silvertone site, Paul Ruben etc. Please keep this lack of technical expertise in mind!!

    Thanks to anyone that can help or at least read this!

    old style PI info

    I just wanted add the link to the G Weber article on harp amps especially on that PI info that he wrote about.

    The PI on the Royale Reverb is just like the one in the Fender Tweed Twin 5C8 circuit. You can find that here under Twin Wide Panel

      Okay - I found the guy that did the schematics on the Bedrock site and he has clarified a lot of things. I will try to get this built in the next month and work on a better layout in case I can help anyone that is curious about this amp in the future.

        It works!

        Its alive!! After sitting on the bench collecting dust for 2 years, I finally got it going! Cool sounding amp! Like a Vibroverb with a Marshall channel. I am fighting with excess ac hum but I think I just need to isolate some stuff and refine some grounding. It is running a bit hot so maybe cool it some with a cathode bias adjustment.

        Its like giving birth with out the pain!!

            I Found the noise / hum problem - sloppy MV lead placement. It just goes to show that stupid mistakes cause hours of head ache.

            I am very happy with this build!! This thing rocks!! It does Fender BF clean to a VibroVerb crunch to a Vox AC 50 grind. I guess it is a Matchless Clubman in disguise.

            I wish it was not so heavy though! I am too old to lug it around. The trannies in a class A have to be so massive its crazy! I even built it with 15mm Baltic Birch instead of 18mm and used a single Jensen Neo 12 and left the 2nd speaker out for now. I think I will get another Neo though since it is only 5 more pounds. I will install casters when I do that addition though.

            BTW what is the consensus on the Neo Jensen's?? I like them a lot and feel they are structually and tonally superior to the regular Jensens being made today. Because I also play harp need the US Fender type speakers and can't use the Celestion toned ones. They are not Webers CE has decent prices and the Webers cost big bank.
