Your question is confusing... you have a Deluxe with 6L6's now? But it's too heavy? Here's the deal, you can convert a DR to 6L6's without being much heavier. It will have more clean sparkle, but it wont be quite a Twin Reverb either. Transformer size matters for clean headroom. And transformers are where the weight is at. So your "Deluxe with 6L6's" must have big tranny's if it's too heavy.
