Hello, have you not done the test with the battery? the HP is perhaps not HS? Well it's up to you to see!! any speaker of the right diameter will be suitable, but respect the 4 Ohms of impedance, or even 8 Ohms, will also be suitable, see on online sites, or get a PC speaker, old transistor post, transistor, etc., will also be suitable.
Hello Jofaur86,
The Tamiya speaker is marked 4 Ohms and 5 watts - exactly the same spec. as the two inexpensive speakers advertised on eBay.
I will be home later tonight and I will use your method of testing - but please explain - is the HP you refer to the speaker?
.......and when you suggest that "the HP is perhaps not HS" ..................does this mean that you think the speaker may not be at fault? ....(what does HS mean?).
Sorry I do not understand your code.
HP is ................?
HS is................?
The speaker that stopped working has no obvious signs of any damage. If it passes your tests, then my original suspicion that the thin yellow and white cables have fractured when they were so badly twisted can be the only other possible problem as the replacement speaker taken from my unmade kit worked immediately when it was plugged-in.
My plan to change the two (yellow and white) speaker connecting wires to the "non-working" speaker may be all that is needed to get it working again (?) but at only £3.63 each I will order a pair of the inexpensive speakers in any case as they could come in very handy as spare parts one day .
Thank you for your help!
Bob.
