Multi tap OPT 2, 4, 8, 16 Ohm...

[TBM]

Hi!

Maybe you got some experience and tips on this...?

My speakers are 4 ohm.
The amp i 300B SET.
The OPT have 4 secondaries in series giving taps 2, 4, 8, 16 ohm...

Fig:
----------- 16 ohm
sec4
--------+
--------+-- 8 ohm
sec3
--------+
--------+-- 4 ohm
sec2
--------+
--------+-- 2 ohm
sec1
----------- GND

Since my speaker is 4 ohm, I will not use 8 and 16 ohm tap...
Is it benefitial/tweak to disconnect sec3 and sec4 (just use sec1+sec2 in series to get 4 ohm) or should sec3 and sec 4 be "playing" as load...?
I only have one (+-) speaker connector on my amp...

Best,
Tom 🙂
