The original LD3141 amplifier chips for the Akai 4000 series are now no longer available.
Currently plenty in stock
There are some out there offering NOS ones… but these are 40 years old too !
Each Akai 4000 has 4 of these and the GX-280 and 1730 has a pair…. and often one will have failed giving no playback or record on one channel. You can also get lots of hiss or crackles when these fail too. Even when working, they are hissy.. the new ones are much quieter.
A lot of hiss can also come from the C458 transistors on the panel too, so its worth changing those.. and if you want some just ask when buying these modules and I’ll send some FOC
I have had a good friend make batches of these here in the UK using decent transistors, to offer them now as an equivalent replacement for the LD3141. Its a delicate soldering job – 9 pins to de solder and then re-solder, so some soldering skills are required.
50+ already out and working fine.. all are tested upon manufacture.
Cost is each… Any amount for 1 postage cost. Discount for quantity (2+ is £20 each).
Worldwide shipping at cost. e.g. £6 to Europe, USA or Canada
£4 to the UK
