Tube choices...........

[neonthecat]

I have no actual measurements as to the power output of either my SSE (with KT-88's) or my EL84-based SPP. But my ears tell me they are not that far apart when it comes to SPL's given my room and speakers.

Oddly enough, the Millett DCPP I built is claimed by Pete to have around 17wpc. I think for a given setting on my preamp, the SSE and SPP both play louder.

Having said that, the DCPP (with it's humble sweep tubes) resolves recorded details better than either of those. If you play a lousy recording through the DCPP, you can really hear how bad it is!

That just means the SSE and SPP have more gain than the DCPP. In other words, for a given amount of distortion, the DCPP is putting out a bit more power than the SSE would but your volume setting would need to be higher for the DCPP to achieve that. Though the difference between 12W and 17W is not much.

As far as the detail...well I imagine they use different OPTs and the obviously have different topologies.

I don't plan to run my current speakers with this amp although I will no doubt try them before I decide on a full range build. I've ordered the SSE board and will begin getting all the parts needed to populate it.

While I build the board ( minus R17 & R27 ) which I may bottom mount with single terminal strips so I can change these resistors if need be, I can spend more time researching iron.

The big Edcors with the KT 88's might fit the bill well given my musical tastes.

Sorry for my confusion about the two boards. Think I have it straight now.

After I built my SSE and started to try various tubes, I added terminal strips to make the resistor changes easier.

Yes, it may have been one of your posts that gave me the idea. I'm also on the verge of ordering some TB 1808's to use in perhaps a sealed enclosure for this amp. See this thread: Tang Band W8-1808 Cabinet
