Anyone have a single el84 PPP OPT?
A friend ran his Gibson GA-30RV Goldtone with only three output tubes. Don't ask why. Does anyone have a suitable replacement. 4-5K ct, 30 watt or more. 4 and 8 ohm taps would be nice. I have an email to Gibson but my bud is worried about sticker shock. Anyone got a single they'll let go? I was thinking of pulling two of the tubes and turning it into a GA-15RV with an 8k tranny I have lying around but I'm a little worried that I would have too much drive for just one pair of tubes.
Thanks in advance, John... |

Drive is the same for one pair of tubes or two, so going to a single pair of tubes with 8K transformer is OK.
But Triode Electronics has a transformer that should work, $35 - 4K to 4/8 Ohms, http://store.triodestore.com/22bastou.html |

Tom, Thanks, that one looks like it would work and the price is right too. While I'm waiting on a reply from Gibson I might try the 8k tranny. I'm not sure if a 75lb 15 watt amp makes a lot of sense but the people who live next door might like it a little better.
