There are many ways to build a valve guitar amp, with many options to consider:

• What output power is needed?
• Which valves?
• What features should be present, e.g. tone control, reverb, etc?
• Should it be a head or combo?
• Does it need to support multiple speaker impedance?
• What physical size?
• Does it require 1 or 2 channels?
• Physical appearance/finish?
