Members mrweems Posted April 18, 2008 Members Share Posted April 18, 2008 Ok. So i've been messing with my setup on my ac30. And i've noticed a HUGE volume differences when having it set for different options from the back. I now have it set at. Modern and Warm. Instead of Modern and Hot. I found the hot to be to bright. Well. When it was set for hot, there was a drastic change in volume on the master from 4-6. But now when on warm to achieve the same volume it has to be put at 8. And there is not much of a volume sweep in loudness when doing this. Tube change? Link to comment Share on other sites More sharing options...
Members melx Posted April 18, 2008 Members Share Posted April 18, 2008 I don't think those switches have anything to do with the valves. Link to comment Share on other sites More sharing options...
Members mrweems Posted April 18, 2008 Author Members Share Posted April 18, 2008 I don't think those switches have anything to do with the valves. Actually they do.Seeing how on the back on i think the two options i'm talking about says "biasing"Usually when you bias an amp you set the valves hot or cold.

"The amp can be run at 22W, giving a warmer sound at lower volumes and prolonged tube life, or 33W for more clean headroom and overall level. You can also switch the PSU capacitors for a looser or tighter response." Link to comment Share on other sites More sharing options...

Members mrweems Posted April 18, 2008 Author Members Share Posted April 18, 2008 These are the options. # Output (O/P) Impedance Select (8 or 16 Ohm);# Output Bias (82 "Warm" or 50 "Hot");# Smoothing (22uF "Vintage" or 44uF "Modern"); I have 16 ohms *(i think, what ever it came set at.), Warm, Modern.

Members melx Posted April 18, 2008 Members Share Posted April 18, 2008 here you go weemster. Output Bias: This allows for specific biasing of your amplifier.Warm: This setting will run your amplifier at about 22 watts clean (before clipping) which issimilar to an early 4 input AC30. What this means to you is that you Link to comment Share on other sites More sharing options...
Members melx Posted April 18, 2008 Members Share Posted April 18, 2008 Do you own an ac30? no but thankfully I have a manual. I went with the Laney VC30 in the end though. Link to comment Share on other sites More sharing options...
Members mrweems Posted April 18, 2008 Author Members Share Posted April 18, 2008 I just found the manual online. It answered my question. I changed my wattage to 22. Which would explain the drastic volume decrease. Link to comment Share on other sites More sharing options...
Members melx Posted April 18, 2008 Members Share Posted April 18, 2008 more.. Smoothing: This changes the values of the filter caps within your amplifier. 22?f Vintage: This setting is similar to vintage AC30s where your sound will be more open and loose.

It just seemed as if it made it literally a hotter signal and brighter. And i liked it a bit warmer. Link to comment Share on other sites More sharing options...
Members TomCTC Posted April 18, 2008 Members Share Posted April 18, 2008 Why don't you keep it on modern/hot and turn the cut knob down? Link to comment Share on other sites More sharing options...
Members mrweems Posted April 18, 2008 Author Members Share Posted April 18, 2008 Why don't you keep it on modern/hot and turn the cut knob down? Thats what i was planning on doing today in practice. I was going to go a few minutes early to play around with my setup. I'm also bringing the SD1 into practice, seeing if it knocks the Hotcake off my board.
