Warm Tubes

I owned cj prem 16 and prem 8a's and Larry1 is correct. After 10-15 minutes the tubes sound fine. Leave them on all day and you will be replacing tubes very quickly

Ditto. 10-15 minutes here. By cartidge takes longer to "warm up" (4 sides of an LP) than my tube pre and tube amp do. Actually the cart is "mostly" ready-to-go after about 7 minutes on the first side, but it sounds a little "flat" and "lifeless" until about 4 plays. After which it starts to sound way more "liquid." But that is probably my POS Music Hall Tracker cart ($79 Goldring Elan OEM?) more than anything else.

I just switched from an Audio Research LS-9 pre (solid state) to a Rogue Audio Magnum 66 (tube). Three things dramatically improved: power-I couldn't believe how much more visceral ooomph was allowed to flow through the speakers! Detail- a nice jump in finesse on strings, cymbals, etc. Warmth- the music sounds more live and is completely non-fatiguing to hear.

Some tube preamps suggest you don't leave them on, such as the Rogue. They use outbaord power supply and a '2 stage' startup with a gentle start for the tubes. To me, the pre sounds fabulous from the get go! As good when turned on as an hour later.

Hi Dave,

If you get the 17LS you'll be in for a treat!

When not listening unit is in standby. When you want to listen press mute button on remote wait till mute button clicks off turn on your amps wait 20 min and its good to go.

Good Luck!

Thanks all, learned alot. The more I read about tubes the more interested it's becoming. Was just reading a similar question on SS on leaving power on 24/7 vice shutting down, unlike in this posting, opinions are all over. Take care, Dave
