Yes for now, but also get the ones I advised to replace. Because 100k Ri limits bandwidth more. The tube and socket have capacitance and the gain gives Miller, so an RC filter is formed. Ri + Rf solder them meeting directly on the socket's grid pin to avoid using wires giving extra capacitance.
Not too far from 100k is 82k and will lose some gain. Live for now with right gain 100k/1Meg and 50kHz bandwidth. Later you buy good quality 63k/560k to replace for more bandwidth. Or even better two 120k in parallel for Ri for more precision. NoDac Zo maybe low but Ra is 7.5K and needs >>>Rf. Also Cout sees Rf as the impedance to drive.
Fortunately I have four pcs. 1Meg. & four pcs. 110K to make 55KNow you say you also found 55k in your parts bin. That can be combined with 1Meg//1Meg i.e. 500k Rf but you need four pieces.
Do you want to say that resistor load is the best?No CCs anode load no gyrator. About 40mA is two channels draw. 20mA each.
Let's see if one BiB can do it for both tubes.....Resistor load works with this NFB plan. If you change load to active, terra incognita. Yes each 6V6 wants 0.45A heater current.
Good work so far, my favorite construction style, just difficult to repair later.Thanks, attached files work in progress
