Before repair or inspection, make sure to follow:

Use specified parts.

The system uses parts with special safety features against fire and voltage. Use only parts with equivalent characteristics when replacing them.

The use of unspecified parts shall be regarded as remodeling for which we shall not be liable. The onus of product liability (PL) shall not be our responsibility in cases where an accident or failure is as a result of unspecified parts being used.

Place the parts and wiring back in their original positions after replacement or re-wiring.

For proper circuit construction, use of insulation tubes, bonding, gaps to PWB, etc, is involved. The wiring connection and routing to the PWB are specially planned using clamps to keep away from heated and high voltage parts. Ensure that they are placed back in their original positions after repair or inspection.

If extended damage is caused due to negligence during repair, the legal responsibility shall be with the repairing company.

Check for safety after repair.

Check that the screws, parts and wires are put back securely in their original position after repair. Ensure for safety reasons there is no possibility of secondary problems around the repaired spots.

If extended damage is caused due to negligence of repair, the legal responsibility shall be with the repairing company.

Caution in removal and making wiring connection to the parts for the automobile.

Disconnect the battery terminal after turning the ignition key off. If wrong wiring connections are made with the battery connected, a short circuit and/or fire may occur. If extensive damage is caused due to negligence of repair, the legal responsibility shall be with the repairing company.

Cautions in soldering

Please do not spread liquid flux in soldering.  Please do not wash the soldering point after soldering.

Cautions in soldering for chip capacitors

Please solder the chip capacitors after pre-heating for replacement because they are very weak to heat. Please do not heat the chip capacitors with a soldering iron directly.

Cautions in handling for chip parts.

Do not reuse removed chips even when no abnormality is observed in their appearance. Always replace them with new ones.  (The chip parts include resistors, capacitors, diodes, transistors, etc).

Please make an operation test after replacement.

Cautions in handling flexible PWB

Before working with a soldering iron, make sure that the iron tip temperature is around 270 . Take care not to apply the iron tip repeatedly (more than three times)to the same patterns. Also take care not to apply the tip with force.

Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power to the unit.

Cautions in checking that the optical pickup lights up.

The laser is focused on the disc reflection surface through the lens of the optical pickup. When checking that the laser optical diode lights up, keep your eyes more than 30cms away from the lens. Prolonged viewing of the laser within 30cms may damage your eyesight.

Cautions in handling the optical pickup

The laser diode of the optical pickup can be damaged by electrostatic charge caused by your clothes and body. Make sure to avoid electrostatic charges on your clothes or body, or discharge static electricity before handling the optical pickup.

 Laser diode

The laser diode terminals are shorted for transportation in order to prevent electrostatic damage. After replacement, open the shorted circuit. When removing the pickup from the mechanism, short the terminals by soldering them to prevent this damage.

 Actuator

The actuator has a powerful magnetic circuit. If a magnetic material is put close to it. Its characteristics will change. Ensure that no foreign substances enter through the ventilation slots in the cover.

 Cleaning the lens

Dust on the optical lens affects performance.

To clean the lens, apply a small amount of isopropyl alcohol to lens paper and wipe the lens gently.

Assemble a HiQ guitar amplifier - circuit diagram – using 6L6 and 12AX7 vacuum tubes

RCA’s first version of this tube was an early octal base tube. Like most with this base it had a metal, rather than glass, envelope. Later versions, including the 6L6G, 6L6GA, 6L6GB, 5881, 5932, 7027, and the final version 6L6GC had glass envelopes, which made radiation cooling of the anode easier.  5881 is next to the 6L6GB. 

The 5881 should be ok with the plate voltages found in most guitar amplifiers designed for the 6L6GC but this is not guaranteed so you do risk blowing your 5881s if you put them in an amp designed for the 6L6GC.

The valve 5581 can be replaced with 6L6 and the substitution for 12AX7 is ECC83

Valves don’t usually ‘fail’; they just get weaker and weaker. The actual age of the tube is not important. It’s how much it has been played. If you play your amp regularly and it’s been a year or more since you had a valve change, it’s almost certainly time to treat yourself to a new set of valves. 

Don’t forget to buy  “matched output pair” valves. This is really important. The matched valves have been carefully selected to be a close match both in gain and bias current. If you’re going to change amp valves always choose ‘matched quads’ if you have four output tubes or ‘matched pairs’ if you only have two.

If your guitar valve amplifier is not sounding quite so good as the day you bought it, change amp valves to restore that beautiful sweet tone.  If it’s sounding a bit flat, thin and lacking in oomph, change amp valves on a regular basis if you want to keep your amp sounding its very best.

If you notice a loss in bottom-end and power, it’s most likely your power valves need replacing.  If you’re getting strange sounds coming from your amplifier, first turn your gain section up, and slowly turn the master volume down. 

If the noises continue after the master volume has been turned down, it’s most likely a power valve. If you turn the master volume down, and the noises disappear, it’s most likely a pre-amp valve.

 If you want to change amp valves always recommend changing the whole set while you are at. It only costs a little more and you know that everything is as it should be.
