In Reply to: RE: SE 2A3 beta follower : 5K primary THD measurements ... posted by Tre' on March 28, 2014 at 18:13:04:
I compared both external AF generator vs. internal signal generator.
@ just over 1W output with 1.327VAC input sine wave:
external AF generator measured : 3.75% THD
internal signal generator measured : 3.41% THD
The internal generator is a bit cleaner.
Still using the 5K plate load and biased at 43mADC on finals.
Why the THD measured lower today than yesterday is a mystery to me.
I might swap in a biplate 2A3 and see anything changes.
