    Beginner: which amp to build?

    How about a N5X British Overdrive amp from https://www.ampmaker.com - a 5W single ended Class A amp with VVR (lowers the voltage to the power amp stage) so you don’ t need an attenuator to get bedroom levels. The build guide is fantastic and explains the components and schematic then guides...

    Modulus JTM50

    I’m following this build with interest as I’m hoping to build a Wrocket this year. Please cover up those naked thermistor legs - they’re making me nervous! All the best with the build.

    Ceriatone 2555 Jubilee lead channel squealing

    In the photo in post #7 the turret connecting to cathode A (first ECC83) looks a little dry compared to others - could that cause instability

    Simple Attenuators - Design And Testing

    Thanks, and if it gets hot with a more powerful amp I could put the case on its side - with a chimney effect!

    Simple Attenuators - Design And Testing

    I’ve been using my first M2 8 Ohm 50W attenuator a lot with my Tweed Champ style amp so I’ve built another one for it. I mounted all the Rs on a thick piece of aluminium and then into a aluminium case made from a shelf from Pete’s greenhouse. The connections use solid core wire - this made the...

    Simple Attenuators - Design And Testing

    Many thanks to JohnH for the design. I’ve enjoyed reading the thread - lots of good tips throughout - thanks to Gene and LordoftheLivingRoom. I’ve kept my M2 8 Ohm build as simple as possible with plenty of space in my recycled bits case (cheers Pete). I bought DPDT switches with large...
