The covers I've ordered from an local acrylic business.

My latest build was a single ended, single stage amp using the 6C45. I used Vishay/Dale RN/CMF/CPF resistors in all spots except for the grid stoppers, which are old non-magnetic Holco H8. Elna Silmic II are used as cathode bypass caps and output transformers are the Transcendar 'budget' models (hand brushed to give a more pleasing appearance).

The sound is incredibly detailed, although not as three-dimensional as my other SET amps. Absolutely no hum or buzz present.

Default 6n1p-ev headphone amp - my first DIY from scratch

Hi all,
This is my first post. I've restored and repaired a few amps in the past, however, this is my first complete build. This amp is from headwize, the Bender design. CRUSHINGLY LOUD! Handle with care.
Came out OK. Detailed sound, even with a slight hum at idle.
Thanks for the inspiration all. Let me know what you think.
