Does a tube preamp use lower voltage, or at least, safer voltages?
No, not necessarily. However, I'm going to try (gain may be too low) the Peter Millet head phone/line amp. It's actually a hybrid pre/head phone amp, using a unity gain buffer (op amp) on the output. The 'low voltage tube' side of things hinges on his use of tubes originally designed for automobile use from the pre- silicon days. That's my limited understanding any way.

Hello Carpenter:
If you want a low voltage tube pre amp you should consider some of the Auto audio tubes. The one that seems to get the most attraction is the 6GM8. I think it has great potential to use in this application.
I am not knowledgable on the design so I hope someone else can help out

Sorry for the duplication !!But I will need just one set!!
Without the proper tools, I find a lot of difficulty casing a project / making a chassis. Things like tapping screw threads are a challenge.
Do you think this premade chassis have enough heat sinking power?

Have also emailed the manufacturer asking for more info.
thanks

The boards will look as in those pics: http://www.diyaudio.com/forums/showthread.php?postid=1230598#post1230598
The amp board has a scoring line and is good for two channels.
The PS board is good for symmetrical supply in stereo setup. If you want dual mono, you will need 2 PS boards.
All boards are gold plated.
The prices include shipping and handling:
Amp board $12
PS board $16
Prices in USD, paypal payment to my e-mail address posted here: http://audiosector.com/contact.asp
All boards will be shipped by airmail, with no tracking and no insurance and I cannot assume responsibility for lost packages. If you need insurance, please add $7 to your order.
I will be ordering PCBs this week. You can pay now or when the boards become available. The lead time is approx 2 weeks.
