Is that ok to ask? I have an SWR Working Pro 400 in a case with a Goliath II cab. Last year we checked all the speakers and connections and recovered the cab in Linex. Hasn't been gigged but maybe twice since. There are no issues with the amp at all. All pots are clean. I love the tone and it is all I need for my purposes (if a little much). If I were to replace it, I would like to get some idea what it is worth. Thank you.
