Recently learned in a thread here at good ole AK about an interesting tube amp called the VPI 299D. VPI principals intended the 299D is a "tribute" to the great HH Scott integrated 299D. By all accounts, owners and reviewers alike, the VPI 299D is a great sounding amp as it should be with circuit design and build similar to the 299D. By adapting some of the design and the 299D handle, VPI set the MSRP at $4000. Not sure how many sold as production run was limited to 100. One thing is for sure, it didn't look like a real 299D. I read the reviews and it looks like VPI did not acquire the intellectual rights to the HH Scott 299D design. If they had, imagine a true re-issue with cosmetics to match. This leads to the question at hand. Who owns the intellectual design rights to classic designs such as the HH Scott 299D? Do the intellectual rights lapse into the public domain after a certain number of years? Personally, I think a HH Scott revival in the middle tube market would be well received.
