Hey everyone i'm new here!
just wanted a quick answer on what exactly the major diff. was between the 2?
sustain,reverb,clarity?
any input would be helpful, thanks!

When swapped in the same amp, a solid state rectifier will usually have a higher output voltage than a tube rectifier. On the other hand, a tube rectifier will have usually have more sag than a solid state rectifier.

Also, the total wattage output of the amp matters. I think that anything at or above 50-watts starts to push the limits of most of today's tube rectifiers. Unless, you run them in parallel to get more mA output. Which really adds to the complexity of the circuit (to insure balanced output between the two rectifiers).

From 2 to 40 watts, like Bluesky stated, a good tube rectifier can really add vintage sag or "breathing quality" to the amp.

Meaning that it will have more of a "spongy & looser" type of feel?

Yup. "spongy, sagging, breathing quality, loose feel" = all the same. More a result of the rectifier not fulfiling the output tubes' demands for instant current during transients -- -like bass runs or heavy chord hits.

Here's the list of rectifiers and their inherent voltage drop. The greater the drop the more the "spongy" feel. Note, also the output DC mA, peak inverse voltage, & and heater current demand of each type:

Thanks! Hope to be getting back to having a tube amp again soon.
