	Tube Sockets
		It is almost impossible to remove a tube socket without damaging the board or the socket.
		Place all 3 sockets in the board, verify that they are aligned correctly, place a flat surface (hard book or another PC board) on top of the board, then flip the whole sandwich over.
		Since the 9 pin socket is shorter than the octal sockets, it needs to be elevated slightly if the board is being mounted directly to the underside of a chassis.

		These interchangeable tube socket assemblies are not only interchangeable with sockets used in housings of the same type but are also interchangeable with sockets provided with any other housing for the same nominal diameter PMT.
		Included in the socket assembly is the appropriate PMT socket of the highest quality available, the fully wired voltage divider network utilizing high quality metal film resistors and ceramic disc capacitors, appropriate high voltage and signal connector and an assembly of precision injected molded parts.
		The use of cables permits reduction of the external dimensions of the PMT socket assembly, thereby reducing the overall length of the PMT housing or PMT cooler.

		With all the tubes in their sockets, the tube covers off, and nothing plugged into the amp inputs, turn the power on and crank all the controls up to maximum.
		If the new tube still glows bright red, there is probably a failed component in the circuitry to that tube, and you should take your amp to a professional to get the problem tracked down and fixed.
		Inspect the shaft on the base of each rectifier and power tube to make certain that its guide pin andndash; the ridge that slides into a groove in the socket's center hole, aligning the tube pins with their proper socket connections andndash; is intact.

	Tube Amplifier Survival Tips - Maintenance - KBápps.com
		NOTE: Because the tube sockets are connected to the very highest voltages in the amplifier, we suggest that the following work be done only be those having the proper knowledge of electrical safety.
		When tubes are changed again and again over time, the sockets female parts begin to stretch and not make good tight contact with the tube pins.
		A common result of cheap tubes failing is that they will take out a screen grid resistor with them (usually located across the inside of the tube socket, or near by).

	Brazing copper tubing: Its simpler than it seems
		In a socket joint, the filler metal doesn't have to be as strong as the copper because the contact area between the tube and socket can be made large (see Figure 2).

		But despite the difference in tube complement, the Allied radio's adapter socket is a useful clue regarding the purpose of the Clarion's socket.
		The radio's schematic diagram carries the notation "In all cases of 6- and 32-volt operation, replace the 43 tube with a 41 tube." While not specifically stated on the schematic, it is apparent that the choice of 6- or 32-volt operation applies to filament voltages only and that a separate B supply is also required.
