Vintage Tube Amp

1970′s Sound City Bass 150. Electric Guitar / Bass Amplifier Head. He bought out most of the Sound City stock when the company went under in 1975. This amp arrived to me in working condition but had no front panel knobs on the potentiometers and I added it right to my collection. Recently (2026) I took it to my current amp tech and he slowly reshaped the filter cap cans with his variac. He also tested all the tubes for shorts, leaks, and trans-conductance. He cleaned and lubricated all the pots and jacks, replaced the power cord, powered it for an hour and checked operation. He says it’s now in great shape but will need a cap job. He noticed there is a substantial hum usually emanating from the lack of shielding on the wiring in the pre-amp and the power amp of the chassis (which is common with these amps). One way of reducing hum is to add more shielding. The more immediate issue and to help reduce the hum is to replace all of the filter capacitors. This amplifier has all the original hardware. You need to understand that the great amps of this era didn’t have master volume controls and needed to be turned up to get the sound you needed in a live situation. And they WON’T cover up your mistakes – they are true player’s amps that reward technique with clear note definition. Finally, please be advised that this is a true vintage guitar amplifier, that will hiss and hum as you crank it up-and it requires periodic maintenance and adjustments by a qualified amplifier technician that is familiar with vintage tube amps. Please understand what you are getting into. During the musical explosion of the 1960′s in London, it was common for music stores to design and build their own equipment for sale at the shop; each neighborhood retailer would try to outdo the other, along with a good bit of copy-catting, of course. This is essentially how Marshall, Orange, and Vox all came to be, and as happens in most free-market industries, competition would arise. Two of the rarest, loudest, and best-sounding competitors were Sound City and Simms-Watts. In the back of one of these West End shops, appropriately named Sound City, Dave Reeves would design and build the SC105 “One Hundred” model amplifier, a high-headroom 100-watt EL34 answer to the Marshall Super Lead “Plexi” head. The Sound City shop was owned by Ivor Arbiter, whose interest in music had been sparked by his father, Joe, a saxophonist with the British big-band led by Harry Roy in the’30s and’40s. The young Ivor began his instrument career working at saxophone repair workshops in and around Soho, and in 1957, he opened his own Paramount woodwind and brass shop on Shaftesbury Avenue-the street that marked the southern boundary of Soho. Ivor was an ambitious young man, and he saw further opportunities with the rise of pop music as the’60s came into view. In 1961, he opened Drum City at 114 Shaftesbury Avenue and the following year Sound City, which specialized in guitars and amps, at 24 Rupert Street. Ivor’s luck ran out with this particular portion of his operation in 1975, when a complicated set of business problems meant his shops-Sound City and Music City (by now in the Drum City location), and Modern Sound in Tottenham Court Road-were swiftly closed. It might serve the buyers purpose to bring up the power slowly with a variac since these used amp heads are over 50 years old and have not been used for a few decades.

Not Working , But 100% Complete. Sound Projects R-203 Guitar Tube Amplifier. This is A Really Cool & Vintage 1960s Sound Projects R-203 Guitar Tube Amplifier that’s in great cosmetic condition over all for its age. Its in the cosmetic condition as pictured, so be sure to view them all (see pics). I tried to take really good pics, so you can judge for yourself (see pics). This amp appears all original other than what is mentioned above, but does not work. The original speaker appears to be in great shape with no signs of deterioration. When this amp came in, the power cord was cut off, as well as the wires going to the speaker. We threw a power cord and speaker wires on it to see what we had. You can hear that it turns on, but the tubes don’t heat up and you get nothing out of it. It doesn’t appear anything has been tampered with other than the speaker wires and power cord. We didn’t try anything else to get this going and just left it as you see it. Please look at all pics… What you see is exactly what you are getting.

The King of British Boost: Colorsound Overdriver. (by Sola Sound) is one of the most powerful and touch-sensitive drive pedals ever built. It isn’t just an overdrive; it’s a wide-band frequency shaper that can take a clean tube amp and turn it into a fire-breathing stack. From the subtle “treble boost” chime used by David Gilmour to the full-blown fuzz-drive of the early 70s, this pedal is a masterclass in harmonic saturation. Why This Specific Unit? Many of these pedals have been crudely modified to accept a DC power jack. This unit has been meticulously “de-modded” by a professional pedal builder. While a mounting hole remains on the side, the. Internal circuit has been restored to its original, pure signal path. This circuit is famous for its massive output volume. It doesn’t just add dirt; it adds. Genuine Colorsound units are becoming increasingly difficult to source in the US. This is a chance to own a professional-grade “player’s piece” that looks and sounds incredible on a board. Because Colorsound pedals use a large-format chassis that can be prone to bending or denting if mishandled, I provide my. Signature Pro Pack Service. Protected against scuffs and moisture. Surrounded by packing paper to ensure it stays stationary during its journey to you.

This is a1960s SOUND ELECTRONICS Corp VINTAGE Bass X-202 Tube AMPLIFIER. Serial #21121 Made in Mineola, NY, USA. I’ve had this underrated amp for almost 25 years. It was in very sorry shape when I got it. The grey Tolex was a mess and the bottom of the case was beat up. I stripped it, filled the holes, and painted it flat ink blue with variegated gold leaf flames for a blues hot rod look to go with my playing blues standards. It would not cost you much to recover it with Tolex if you want the original look. It has the original exterior hardware and speaker cloth but I added a pair of rails to the bottom to keep it off the floor. The Jensen 15 speaker came from CAE in San Mateo, CA as the original was torn. I replaced some resistors, diodes and capacitors. The power cord is probably not original. All the controls appear original: On/Off, Bass, Treble, Volume, Polarity, plus 3 inputs and one external output. And the little blue power indicator works. And it has an internal fuse. I made the schematic of the amp circuitry that I will include. It weighs 42 pounds and is approximately 28x20x11. I read that Sound Amps were made in Mineola Long Island NY in the 1960s by John Dougherty, a former Ampeg employee, who later went on to run Marlboro amps, made by MICA (Musical Instrument Corporation of America) in Syosett. The Sound amps were made really well & used similar circuits to Ampeg & Oliver units. Dougherty also invented and patented the Quadra-Sound Blender, an outboard effect, which combined tremolo, vibrato and reverb, to produce a couple of unique surf-like effects.
