Mark III Driver Board - R16 Question

Hi,

Started putting the components on my Mark III VTA driver boards and came across something that has me guessing.

In the parts list R16 (6.8K) is listed only as a 1/2W resistor, yet I wonder if this is not supposed to be a 2W rated resistor similar to the other resistors in this part of the circuit (ie R20 R22)?

Can anyone confirm the correct wattage for this resistor?

Thanks. SoundBound

I have seen that listed variously as 1w or 2w but never less. I would err on the side of the larger rating especially with newer resistors being smaller than vintage Carbon Comp.

Thanks Bob and Snav;

I am building the lower gain version with the 12AU7s, so it makes sense to me that the 1/2w resistor is a bit low, I will go ahead and substitute a 1W or better for the 6K8. Maybe if Roy sees this post he can correct the documentation for the low gain version.

yes, should be a 1 watt, if I sent you the wrong part email me directly and I'll send you the correct part

Hello Roy,

I purchased the bare boards, supplied my own parts. The confusion is in the documentation (VTA MK3 v11 LG manual.pdf) for the low gain configuration, R16 does not have a wattage specified in the parts list, thus as per all other resistors where wattage is not specified, 1/2 watt is understood to be the wattage value. This is the error, it should be marked as a 1 watt (according to Bob and Roy).

Bob is correct, and I have updated the manual to show that resistor is a 1 watt
