Re: '68 Super Reverb slight buzz on note decay help.

Good guess, but I wasn't paying thru them. Was using a cab with old Celestions. I recently had those original CTS's reconed. They're AlNiCo and sound very sweet, though not real efficient. But who needs efficiant with a Super? Going to double check tonight before I put it all back together.

Re: Tweed Deluxe Pre-amp voltages

Thanks. I actually am using a 5v4. I also replaced the 22k resister in the power train to 10k, which got the preamp voltages up a little and improved sound, but not a lot. 5K is too low and I get bad distortion/inadequate filtering. Any other suggestions?

Tweed Deluxe Pre-amp voltages

I have a Tweed Deluxe 5e3 clone with a Kendrick PT which puts out about 330V from the secondary. My preamp tubes are running at about 140v. Is that where they should be? Seems awfully low compared to the 170v-180v in my '66 Deluxe Reverb or 270-280v in my '68 Super. None of the schematics I have fou...

Re: '68 Super Reverb slight buzz on note decay help.

Xtian: seems worse with volume, but sometimes on low volume. Weird thing, at low volume the buzz starts sooner.

Re: '68 Super Reverb slight buzz on note decay help.

2W? That is overkill, but if it works-do it! I don't use carbon comp. resisters, but I will make sure they've been replaced. I don't get why the Vintage Police are all about them. Some old things are better, but some not so much.

Re: '68 Super Reverb slight buzz on note decay help.

I will check the plate resistors. Any particular coupling caps to suspect? I guess I can go through subbing out each one. By "bacon frying sound" do you mean what's also referred to as "snap crackle pop" from plate load or other failing resistors?

'68 Super Reverb slight buzz on note decay help.

Hope I can get some help. On my'68 drip edge Super: Amp is strong, loud, totally tone worthy. Problem is: as a chord decays, there is a slight fuzzyness. It will often go away as the notes continue to decay. Sometimes it happens on the attack side, but mostly on the decay. All the caps have replaced...
