Sign InQ. I see that the dimension for the amplifier / speaker is 66mm but would that be the size for the hole in the acrylic if the speaker is to be inserted? I want it to be precisely made so it doesn't look shoddy. Using laser cutter for acrylic
A. Hi Gemma, thank you for your question. If fitted from the rear, a 60mm hole would be needed.
Q. Please is it possible to fit smaller diameter speakers with this Amp, e.g. RVFM LP50028A PAPER 8 Ohm 50mm Ultraslim Paper Speaker 0.2W (35-0128) If so can you provide a straight substitute within the kit?
A. Hi A Benton, thank you for your question. The kit will work with virtually any 8 ohm speakers, however, the lower the power handling the more likely the smaller speaker will distort or be damaged if over driven.
Q. What is the speaker wire? Is there an order code for some extra, please.
A. Hi R Castley, thank you for your question. The speaker wire used in the kits is 01-0162.
Q. is there an instruction booklet for the construction of the mono amplifier
A. Hi P Burton, thank you for your question. The teaching notes can be found here.
Q. Can this be powered by a USB connection? and can a volume control be added. Thanks. Roger
A. Hi Roger, thank you for your question. The circuit will work at 5V, however, the current draw at loud volumes may overload an already used USB device so caution is recommended. The kit is ideally used with a mobile phone/MP3 player using its own volume control. You can employ a potentiometer between pins 3 and ground of the TBA820M replacing R3 in most cases this is not necessary.
Q. Are the circuit boards pre-drilled?
A. Hi Steve. Thank you for your question. The supplied PCBs are pre-drilled and are available as spares as well in packs of 5 (70-0190).
Q. Does this kit come with the jack leads shown in the box? Thanks Simon
A. Thanks for your enquiry - Yes the jack leads are included with this product.
This pack contains all the items required to make a fantastic little amplifier and speaker. The amplifier and speaker assembly can then be incorporated in a housing designed by the student, further extending the learning available. There is ample instructions available online to help the students achieve a good result and a worthwhile project to take home.
We bought a set for a community group kit building event. The kids loved the end result and most worked first time. They proudly went home to show parents and grandma what they had built, and it worked! This was due largely to excellent PCB design, comprehensive building instructions and quality components. This is not an Asian kit with parts and instructions missing! Can be built by a youngster from 6 to 16 with ease. We've been amazed at the quality of their soldering. Well recommended. We'll now look more closely at the other educational electronic kits that seem to be very reasonably priced. Thanks Rapid from all of us!
This is a fantastic class pack that offers superb value for money. I have used this item for the past 5 years with fantastic success, with the pupils soldering fully working speakers each time.
Very comprehensive instructions and the teaching resouces are carefully planned and much time taken with the graphics.
