Summary
[edit]DescriptionResurrected ugly sisters - DIY tube amps from 1990s 2.jpg |
English: A pair of DIY tube amps (6C45P - Lundahl IT - 6C4C PP - Lundahl OPT) I built back in 1990s. Then the power transformers died, and they were left unattended for around 15 years - until I finally replaced the transformers. Yes, it's ammo-grade brass faceplates, bolted to aluminum L-rails. And in real life they're not that ugly. |
