High Quality Phono Sockets.
High quality gold plated phono sockets with teflon insulator and gold plated contacts. Requires an
10mm diameter drill hole when fixing to a chassis.
Stereo Pair of Phono Sockets = £4.50.
Op Amps
Burr Brown Op Amps.
Single Opamps
OPA134PA DIL = £2.00.
OPA604AP DIL = £3.80.
AD843KNZ DIL = £8.00. Very high quality opamp for use in CD players - not for use in the Quad 405.
Please see here for further details.
OPA627AP DIL = £15.00. Please email before purchase to check stock.
Dual Opamps
OPA2134PA DIL = £3.65.
OPA2604PA DIL = £3.80.
AD826AN - The ultimate dual opamp = £8.00.
High Quality Turned Pin IC Sockets.
High quality, low profile Turned Pin IC Sockets with gold plated contacts. Ideal for upgrades where substitution of opamps may take place.
Price excluding P+P = £0.50 each up to 5, £0.40 each for 6 and over.
High Quality Gold Plated Turned Pin IC Sockets - Up to 5.
High Quality Gold Plated Turned Pin IC Sockets - Six and Over.
High Performance Diodes.
High speed, soft recovery diodes. These diodes have a very fast, soft turnoff characteristic and minimise switching spikes and RF noise when used in bridge rectifier circuits producing a quieter background and improved detail and dynamic range. Do not bypass with snubber capacitor.
UG06B - 0.6A 100v soft Recovery - 15nS turn off time. £0.35 each.
11DQ10 - Shipped as 11DQ09 - same diode but rated at 90V - 1.1A Schottky diode - £0.60 each.
Very fast recovery and minimal switching transients for low noise bridge rectifier circuits. Will directly replace 1N400X series of diodes as used in CD players, preamps etc.
Replacement Quad Transistors.
BC214 (BC154 on Quad 303) - £0.20 each.
BC109B - £0.70 each.
BC546B (U17219 on Quad 303) - £0.20 each.
BC556B (U17229 on Quad 303) - £0.20 each.
BC441 (38495 on Quad 303) - £1.60 each.
BC461 (38496 on Quad 303) - £1.60 each.
The heatsink top cover on the 38495 and 38496 transistors should be made flat
(around the transistor hole) before replacing when fitting the BC441 and BC461
transistors as there is no heatsink flange in the more modern devices. This is
to ensure that the transistor is in good thermal contact with the heatsink.
Tube of Heatsink Compound Paste. This paste is applied on
either side of the mica washer to aid heat conduction to the heatsink and is
the most reliable method of mounting power transistors to a heatsink but is a
little messy compared to silicon washers.
25g Tube of Heatsink Compound = £3.20
Solder
High quality Silver Loaded solder (3.8%). Listening tests were done on a number of
different solder types and this was found to be sonically the best of the bunch.
As it has a higher silver content it has a higher melting point and is harder than normal
solder so requires more care in use. More difficult to remove parts which have
been soldered with this solder due to the higher temperature needed to melt the
solder, so can lift tracks if not done correctly. Makes very strong joints. Manufacturers recommended soldering iron tip temperature is 360 degrees centigrade.
Internally fluxed.
Silver loaded solder 0.5mm £0.90 per meter.
Silver loaded solder 0.8mm £1.00 per meter.
Interconnect Wire
Silver Plated single core OFC copper wire with PTFE insulation. A cable which can be used for connecting the inputs of the 303 or 405 to
their input phono sockets of for other signal routing in preamps etc. Very good sound quality for the price, far superior
to the original screened cable originally used. Makes a noticeable improvement
to the sound quality when used with a decent quality signal. Can be twisted with
another colour to produce a signal cable.
PTFE Insulated Interconnect Cable Red - £1.40 per meter.
PTFE Insulated Interconnect Cable White - £1.40 per meter.
Power Wire
Silver Plated 19 x 0.2mm strand OFC copper wire with PTFE insulation. A cable which can be used for connecting
power lines and speaker connectors etc inside a power amplifier.. Very good sound quality for the price, far superior
to the original copper cable originally used. Makes a noticeable improvement
to the sound quality.
PTFE Insulated Power Cable Red - £2.50 per meter.
PTFE Insulated Power Cable Black - £2.50 per meter.
PTFE Insulated Power Cable Green - £2.50 per meter.
Push On Connectors
Standard Quad type connectors for fitting to the power cables so that they
can be connected to either a standard Quad 405 amplifier board or a NET
Audio 405 MK3 amplifier board.
JST Connector £0.11 each.
