Discussion Overview

The discussion revolves around the request for a schematic diagram of the ROYAL L1200 power amplifier. Participants explore the need for such a schematic in the context of repairing or understanding the amplifier's design.

Discussion Character

  • Homework-related
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant requests the schematic diagram for the ROYAL L1200 power amplifier.
  • Another participant notes that the schematic may be proprietary and questions the purpose of the request, asking if it is for repair or reverse engineering.
  • A participant expresses intent to fix a related amplifier but does not clarify what is meant by "related amp."
  • Another participant suggests that fault finding typically does not require a schematic and asks for details about the amplifier's components and symptoms.
  • A link to a site with similar schematics and photos is provided, but it is unclear if it directly pertains to the ROYAL L1200.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the availability of the schematic or the necessity of having one for troubleshooting. Multiple views on the need for a schematic and the approach to fixing the amplifier remain present.

Contextual Notes

Participants mention the potential proprietary nature of the schematic and the variability in amplifier designs, suggesting that similar amplifiers may share internal structures with minor differences.

Welcome to PF.

It looks like your question on allaboutcircuits.com isn't getting replies either. If you can't find it with a Google search (like I'm not able to find it), then most likely the schematic is proprietary. Why are you wanting a schematic? Do you need to fix one, or are you trying to reverse engineer it?

I don't know what that means. Which "related amp"?
 
Fault finding does not usually need a schematic diagram.
Most amps are the same on the inside with only minor changes.

What power transistors are used, and how many per channel ?
Do you know when it was built, date codes ?
Can you produce a photo of the circuit board and the power supply.

What are the symptoms ?
There are several people on this forum who can tell you what to check next.
