Amplifier board for Harman Kardon SUB-TS11 (HKTS 11 / HS 300)

The SUB-TS11 is the 200 W RMS powered subwoofer (10-inch driver, bass reflex) of the HKTS 11 speaker system, which was bundled with the HS 300 home theatre receiver. The original service manual dates to March 2008 — this platform is older than the HKTS 200 series, and original spares have been unavailable for years.

The amplifier exists in our production data as bare-board drawings 104-A05276A00V-E and 104-DS15000V. Because the customer base for this model skews towards original owners keeping a complete system alive, demand is steady even at low volume — and there is effectively no competing supply.

If your SUB-TS11 shows a dead or protection-cycling behaviour, contact us with a photo of the board inside your unit: there were production variants, and we confirm the correct revision before you order.

Questions that come up before a first order

Will this board fit my unit without modification?

Yes, if your model appears in the fitment list above. The boards are rebuilt from the original production drawings, so footprint, mounting holes and connector set match the original. If your model is not listed, use the model matcher or send us a photo — we answer before you order.

What warranty do I get?

24 months from delivery against manufacturing defect, for both consumer and trade buyers. A board that fails in normal use is replaced rather than debated.

How do I know whether I need the power board, the amplifier board or the control board?

Measure the supply rails first. If the correct DC voltage is present at the amplifier input, the supply is healthy and the fault is downstream. If the unit is completely dead, start with the supply — and remember the control board supervises start-up, so a replaced supply that still will not start points at the control board. If you are unsure, send us a photo and we will tell you before you order.

Do you ship outside the EU?

Yes. We ship worldwide, but EU and UK orders ship from local stock with duties and import VAT settled by us. Orders to other regions may attract local duties payable on delivery.

Can I buy a single board if I'm not a business?

Of course. Trade pricing starts at 10 units, but private customers and individual technicians order single boards every day at the retail price shown.

Repairs on mains-powered equipment carry a serious shock risk

Repairs on mains-powered equipment carry a serious shock risk. Work only with the unit unplugged and the reservoir capacitors discharged, or leave it to a qualified technician.
