I want to build my first amp. I would like a stereo tube amp kit to start with. I am after a kit that contains all the parts so i can have every thing on hand and instruction for my first time. can any one help. i have seen the 300b that looks nice but very costly.
Thanks
Todd

Things we need to know:

What is your budget?

What is your prior skill level with kits?

What will you use this for (music, home theater, how loud)?

What speakers do you plan to drive?

What are your expectations?
 
Do a search for Pete Millets engineers amp. The basic transformer set is available from Edcor and the tubes are available for a fair price. Yes it is a PP amp but you will enjoy the triode connected outputs. The board is available off of fleebay for around $50 US. If you use 6GV5, 6JM6, 6JN6 outputs they are rated at 18 watts dissipation or the larger 6LB6, 6LF6 etc... that are rated 35 watts. Output power has a wide range depending on the iron selected. If you want more power, just up the B+ and use larger output iron.... Enjoy
 
Here's a beginners kit, the K502, everything except the chassis. Need to check it matches Aussie mains voltage. It's starting to get a bit dear though.

Find kits in the left hand menu then go to audio for the K502.

Personally I would find an old valve amp console and refurbish it while your swotting up on theory. An EL84 or ECL86 push pull amp would be ideal for rebuilding later to a modern design. In the long run this would be the cheapest option IMHO.
