    Pioneer A-88X

    Turns out it was just loose set screws, two of them and a 1.5mm Allen key was needed to set things right. However, the amp now has another problem...a dead left channel. C'est la vie.

    Pioneer A-88X

    Maniac, What sized allen key did you need to get the main volume knob off with? I've only noticed now that mine just spins a full 360deg and feels very loose in hand. I'm hoping that the set screws just need tightening and that the volume pot itself hasn't been destroyed (I suspect by the hand...

    Using A-9’s to Bi-Amp Infinity Kappa 8 - Thoughts on pre-amp to use?

    I’ve swapped out the damaged Polydome with a set of “aftermarket” ones and hooked it to my 777. It’s 8:45pm here and me and the cat are the only ones up, but Midnight Oil on CD sounds good with the loud dial barely off the stop. So far so good.

    Using A-9’s to Bi-Amp Infinity Kappa 8 - Thoughts on pre-amp to use?

    I have an A-9 and an A-777 at my disposal plus a Yamaha RX-A2A Aventage receiver.

    Using A-9’s to Bi-Amp Infinity Kappa 8 - Thoughts on pre-amp to use?

    Most, if not all, posts I’ve seen about driving Kappa 8’s is that they need high current Amps of various makes to be able to use them to their full potential, using two to bi-amp, mainly due to the power hungry woofers.

    Using A-9’s to Bi-Amp Infinity Kappa 8 - Thoughts on pre-amp to use?

    Background The person I bought the Kappa 8’s from was using a pair of NAD C272 amps and an Atoll PR 200 pre-amp. Situation I have a pair of A-9’s I could use but no pre-amp to interface CD/TT/Deck into the Amps. So my question is: What Pioneer pre-amp of suitable lineage to the A-9 would be...

    Infinity Kappa 8's Missing Base - Need to buy or Dimensions to Fabricate?

    If I may, what size bolts did you use to attach your base to the speaker?

    Pioneer A-88X - Main Filter Caps looked "bloated

    You are spot on! The tops did readily move under thumb pressure and pop back into place, so they seem to be ok. Thanks for your insight.

    Pioneer A-88X - Main Filter Caps looked "bloated

    "Hello all, Just received this machine the other day, it's exhibiting issues with front panel switching needing a good clean. So, off came the lid and I noticed that the four main filter caps (71V, 10,000uF) had stripes on them. It took a few secs to realise that they were touching the lid and...

    Do you have any pics of the internals, especially the big filter caps? cheers Les

    Converting input voltage from 100/110/120v to 240v

    You are spot on, I do have a few step down trannys that the local US embassy were getting rid of, but they are quite clunky, still they do allow me to use US sourced gear.

    Converting input voltage from 100/110/120v to 240v

    My intention was to change out power supply components to meet the input mains voltage. The simple way would be to use a cct diagram from a 240v variant and replace components as needed. The trick would be the transformer of course depending in the input/output windings ratio and it’s power...

    Converting input voltage from 100/110/120v to 240v

    Hello, I’m wondering if it’s conceivable to alter the power supply of a piece of gear to enable a different input voltage to that originally designed? Has anyone done such a thing? Are there “mod kits” or instructions out there that would enable such a change to be done? All discussions...

    CT-F1000 - No tape transport movement

    I've run my fluke over the switches with the cassette holes taped over and they seem to making/breaking as expected. Do you happen to have the expected voltages with/without a tape per pole? CHeers.

    CT-F1000 - No tape transport movement

    None taken, it's state of maintenance is as is straight out of the packing box, have no fear it needs a clean! No amount of actuator switch (top centre and right bottom) depressing gets any movement from the transport

    CT-F1000 - No tape transport movement

    Hello! This machine is a recent purchase from across the pond, a 120VAC model. It power up, belts are intact, and I cannot find any broken wiring via a visual inspection. The CrO2 light toggles by manually activating the selection switch up in the top of the tape bay. It's quite clean inside...

    Connect EQ Expander Reverb to Preamp

    I've used Option 2 top connect up my A9/RG-9/SR-9/SG-9 and what a revelation!! I've given up so many times whenever I connect these up using the manuals setup diagrams, that they just sit there doing nothing. Finally I have it all working! Thank you so much for making it seem easy.

    Denon DRA-275R - Issues with surface mount function switches

    Hello all, My Denon receiver has issues with the function (input switching) switches not selecting correctly. The front panel display shows whichever switch I've activated (e.g. select Video, Video displayed) but I need to keep pressing buttons until an audio source is heard, independent of...

    Pioneer ct-s830s

    I'll second that statement, using the FLEX function clarifies the sound immensely. I've just installed it into my rack and it made a 42 yr old copy of Gerry Rafferty's "City to City" sound like it was brand new.

    Pioneer A-9 Left Channel Fault

    I've successfully adjusted the power amplifier voltages, the following was observed: The 50mV setting was reasonably stable, however the 75mV setting drifted somewhat by 10-15mV until I left that machine to warm up. The Preamplifier (EQ Amplifier Assembly) were also successfully adjusted, the...

    Pioneer A-9 Left Channel Fault

    Thanks mbz, now that you've said it that way, the adjustment table in the service manual makes more sense. I've seen that the VR's can be a touch fragile if they are sticky, which I would assume if after many years they haven't been touched. Should I apply a drop of deoxit onto them before...

    Pioneer A-9 Left Channel Fault

    UPDATE Have ripped the top off and with no inputs, volume to zero, line straight selected, no load and VR1 - 4 untouched I measured the following: L Ch - across pins 21(+L) and 20(-L) = 79.5mVDC R Ch - across pins 19(+R) and 18(-R) = 87.5mVDC, using a Fluke 73. Prescribed values are 50mVDC &...
