I'm looking to build a desktop headphone tube amplifier and need some recommendations. Ive been researching plans for a few of the kits, the most popular seems to be the "Starving Student" amp. In reading through some of the information I've found, I've noticed that people are driving some headphones with fairly high impedance's. I'm very entry level into the Hi-Fi world and am currently using some Denon AH-D500 headphones. Some like em, some hate em. In any event there great for me right now. The input impedance is 25 ohms with doesn't seem like much compared to some of the setups I've been reading about. Here is my wish list......
- Tube amp design - Utilizes fairly easy tubes to source
- Capable of safely driving 25 ohm Denon AH-5000 without overloading them
- Sub $200
- Very well documented plans
- Straight forward design for Nubie/Amateur electronics hobbyist (I can run a soldering iron well)
- Simple and fairly compact
- Will last years and years with minimal tweaking
That's the wish list, now how close can i get? Honestly I really love the "Starving Student" for its simple design and small footprint. This one really got my creative juices flowing. My issues are I to make sure I'm not going to kill my headphones, and I've heard the 19j6 tubes are getting harder to source these days. I want to make sure i can enjoy this for years to come!
