Vintage 1960s Carlsbro CS100 PA Reverb Guitar Valve Amplifier Rare Transformers

We've had a couple of Carlsbro amplifiers in in our time, being so close to the original shop, but this is one of the nicest examples by far. This amplifier comes complete with the original label to the back, and is in wonderful condition and originality. These early Carlsbro amplifiers are renowned for having similar transformers to the mid to late 60s Marshall amplifiers - this is one of them. One of the knobs has been replaced early on, along with a couple of the feet, and the Bulgin has been changed for a modern IEC. The previous owner had a set of JJ EL34 valves installed, and the ECC83s are 2x Brimar and 1x other, along with a few small components on the circuit board changed. There are a few scuffs to the exterior, as pictured. Please check out the in-depth pictures below as these form part of our description.

This amplifier has been serviced to a playable & safe standard, by one of our leading amp techs. To find out more about what our service includes, please check out our terms and conditions before purchasing.

At The Music Locker we will do all we can for you to get the instrument you want. You’re more than welcome to come and have a play on this, coupled with one of our vintage guitars!
