Up for sale here is this pair of used vintage 1949 250k ohm linear taper potentiometers. I don’t know who made these–each is marked “4-62, ” but that’s a part number, not a date or EIA code. These have short 1/4 round shafts. They test around 271.9k ohms and 254.7k ohms, so fairly close. These are very r are potentiometers and will work great for you, though they may need some Deoxit. These are for amps–they are probably too big for a guitar. Please see my pictures for details. If you have any questions, please ask. I have more potentiometers and other vintage electronics listed–feel free to take a look!

Here is a SUPER rare amp to find in the US – the UK made Linear Conchord! This one is in need of a rescue. This is a 30w amp designed to run a GZ34 rectifier tube, a duet of EL34 output tubes. These were the poor guitarists amplifier and were originally metal caged mono block looking amps available on the cheap to British budding guitarists. This one has an INCREDIBLE looking custom made cabinet to house the amp. This one has a US plug installed and no tubes and in need of a re-cap at the least. Currently the chassis is not mounted in the custom cabinet so I will have to pack carefully to keep it from rattling about. Very cool piece of British amp history with a great looking custom made cabinet. Available at Sunflower and Friends in Lockhart TX.

This is not available for international buyers. I will almost certainly send it in two separate packages since one piece is extremely heavy. You get all three pieces as seen in the first photograph and then I give you a lot of detailed photographs of each piece. There is a complex cord that looks like the pin output of a vacuum tube that goes between two of the pieces. Very rare amplifier setup with separate control module and preamp output stage. The backbone of this system is the valuable TO-300 transformer which is labeled as an 18 Watt output variety. There’s a complex interconnect cord as well as a four prong cable that connects the two units together. I don’t dare test this or plug it in because I know a lot of people like to test these on a variac. I give you a lot of photos there is some discoloration and wear on the metal chassis of both units but the toggle switch moves freely into its three positions and the tube plugs don’t look cracked or damaged. Half of the knobs on the control unit turned freely and some have meaningful resistance. You can see some framing of the four prong cable but you’ve got multiple RCA outputs and a power lamp indicator the primary tubes on the larger unit are ge 61-43 / 188-5.
