The major downside of the X-101-C is that under the chassis is very crowded. The chassis has very little vertical room since it was apparently designed to be a low profile amplifier. It makes doing very many modifications a challenge. Dave Gillespie worked wonders with this design given the limited space available. I agree that Fisher's 7591 equipped amplifiers sound great and have enough power to handle lower efficiency speakers better than the 6BQ5/7189/EL84 equipped amplifiers. However, for people with limited budgets years ago, the 6BQ5/7591/EL84 amplifiers did a decent job of reproducing the audio spectrum when paired with reasonably priced speakers of the era. My first amplifier was a Heathkit EA-3? a 12 watt mono amplifier using 6BQ5 tubes. I worked in the HS cafeteria to save up money to buy it and put it together. I was proud of the results. That was a learning experience for me as a teenager. I built a number of Heathkits and Dynakits over the years.
Have fun!
