My latest winter project is moving right along - a guitar amplifier using a design from the 1950's. This circuit is noted for its "singing" qualities, it isn't really very loud, and in fact I'll be making it with lower voltages- probably only an 8 watt output vs. the usual 12 watts.
In recent years there has been the development of a cottage industry servicing thousands of amp-makers. This particular model, with its unique tone, has been so popular that the original manufacturer has reissued it- with a $2700 price tag! Needless to say, mine will cost considerably less. What can't be figured is the time I'll spend assembling it. This time spent is not a debit, it is completely enjoyable- like a four dimensional puzzle, with the addition of potentially lethal voltages!
