    I have a Technics Pre Amp Model SU-C800UE-K, that gets power from the matching Power Amp SE A900S through a special cable provided for the purpose. I now need to replace the Power Amp due to its malfunctions.
    Is it possible to run this pre-amp without the said power Amp? I envisage purchasing BRYSTON 3B SST to replace the defective SE A900S.

    The only one I can find at the minute is on a Polish website. I copied the web address below and pasted it in to Googles Translator from Polish to English. You can may be figure out a way to contact them about it. The address is:
    http://sklep.north.pl/szukaj/szukaj.php?...

    The translated address is here:

    Make sure you copy and paste all of it up to and including the final 8

    Will still look around for more sources.

    As long as the output signals from the pre-amp are ok for the power amp, they should be if you can work out which wires from the pre-amp goto which inputs on the power amp. The only other thing is to find out the voltage from the original power amp that powered the pre-amp and get an equivelent power supply. It may be 6v, 9v, 12v etc. You will also need to find out the current requirement for the pre-amp. That may be in milliamps something like 500ma or even 1amp or more. If it's not correct the pre-amp will try to take the power it needs from the supply and if the supply is not strong enough it will burn out or blow any fuses in it. If you have the user manuals it may tell you in the specifications.
    I have a service manual for the power amp but not for the pre-amp.

I will buy a Technics se a900s amplifier, but


I think you are saying you want to connect the amp and use it's vu meters but not connect it to speakers?
Presumably you are already well catered for in the matter of amplification but lacking good vu meters?

There is a fair amount of information about this premium amp online including operating and service manuals that can provide a better answer than I can.

One note of caution; it is generally bad practice to operate a power amplifier without a load at the output and it might damage the amplifier. If it is desired to operate it without speakers providing the load, dummy loads are available.

I suggest you have a look through ebay or Amazon where you might find digital or analogue vu meters at a reasonable cost or alternatively I believe computer software could turn your laptop into vu meters.

Good day i have a Technics amplifier SU-X320. Problem is it powers up up there is no sound. Checked all basic fault finding, suspect it is the volume IC.


"Volume IC" do you mean an IC that is a pre-amp and controls the volume and things like tone? Or do you mean the main power amp IC, which will be on the big heat sink?
If you amp uses the latter and not individual separate devices for the power amp, suspect that over the other IC. But if the amp has separate power amps for both channels, replace the IC.

I would have the power supply capacitors replaced. After several years ( from heat and age) they dry out and dont put out proper DC voltages to run the amp.

Technics amp SU-X999. I need an output I.C type SVI-4004


NAother option is to fix a universal amplifier kit into the set which powers from the same voltage preferrably a MOSFET drive which are very much available in the market and can be suited into the set. They will alos be very effficient but take care tto do the fixing mechanically , connecct the right power and groung with good shielding. Disconnect the old amp totally and use the power lines that come to the IC. I hope this works for you. Good day

Same problem


The overload indication tells us that there is a problem in the final stage of the amplifier section. This model uses an AMP-PAC or large amplifier IC (part number RSN-3305) which is now defective. If you can solder, try resoldering the pins on this IC. Sometimes a poor solder connection can cause a voltage offset that will be detected as a fault and shutdown the system like this. If the resoldering fails, the IC will need to be replaced. Parts cost will be in the $75-$95 range.

My Technics DV-170 shows F61 Error when i try and turn it on?


That is a protection indication. This means that the output amplifier section has a problem that was detected and a shutdown occurred to prevent further damage. I don't have a listing for your model, so I can't provide you with too many details, but look for a large black IC attached to a heatsink. That should be the output amp pac. If there is not one, there should be 4 3-legged parts (transistors) and one or more of those may have failed. I have also seen cases where a voltage regulator that supplies the driver circuits has had bad connections thereby shutting down the driver circuit.

Keep us posted.

Technics SH-AC300 Connection to Power Amp & Pre-Amp


Hi!
The problem is, that your SH-AC300 needs an amp with 5.1 input (but no decoder). For this purpose technics delivered SA-AX710.
So if you'd like to use your current equipment it would be impossible.
The only option is for you to buy 2 more Power Amps (SE-A900S), so that each of 3 amps would take care for one part of music. (one for FL, FR; one for RL, RR; and one for sub and center).
Another option is for you to buy SA-AX710. Then all the problems would be solved with it.
