    I've been getting ads on my Facebook page from

    They offer a set of tubes for the Ampeg V4B H amplifier.

    I have a 1974 V4B 100 watt Ampeg.

    Will that be the correct set of tubes for that amp too?

    Those are not the right tubes for your amp. The V4BH uses a quartet of 6L6GC power tubes, your amp uses four 7027A tubes.

    From the tube store, order four matched reissue Tung-Sol 7027A's: - Tung-Sol 7027A Audio Tubes.

    I have a 74 V4B as well. Very nice amp. Below is the '74 schematic.
