Looks great! What is the finish on the neck like? I know they often used the same necks across many models, but some are finished differently.

Not to start a troubleshooting thread, but is this buzz apparent in any of the DI signals, specifically when the amp is run loudly into a cab (i.e. cab vibrates head, is the buzz in the DI signal)? It can be hard to hear any high frequency content in many cabs.

Issue was with the filtering in bias supply I believe. https://www.talkbass.com/threads/ampeg-pf-50t-humbuster.1306043/ Ampeg PF-50T Humbuster Again, was just trying to chime in on the post dissuading people from the purchasing the amp based on an issue that has (to my knowledge and experience)...

Not to add yet another bit of speculation, but didn’t they already fix this years ago? I just bought a PF-50T (serial code dates it to 2023) and there is very, very little hum. Some still there yes, but it’s comparable to all other tube amps I’ve heard and played. I should note that, having also...

No; no sound comes through the speakers on standby; I could be wrong but aside from the heaters, I don't think anything is actually 'on' when in standby. Output transformer is to the left, closest to the speaker jack. Power transformer is to the right, closest to the power input. These did...

Update: did a lot more testing and found that, as you all suggested, it is in fact likely just the tubes that are microphonic. One of the power tubes seems to be the largest culprit, and it seems V2 and V3 preamp tubes are also slightly microphonic. My current guess with knocking on the...

Believe it or not, the hum on this unit was, in my opinion, very acceptable. It was completely unnoticeable when playing at volume. Some hum is definitely present, but it is fairly quiet. I have yet to open it up, but doing the mod was definitely on the docket assuming all else was in order...

Hi all! Just recently picked up a PF-50t from Zzounds that was labeled 'scratch and dent'. It was roughly 30% off, and they didn't provide any information about the actual condition, no photos or comments on the supposed scratches and dents. I decided to take the 'risk' anyway, but they have a...

I'm very confused by this post - you claim "result was unusable transformer line out channel" and then conclude on the second day that the very same setup works with no issue. On the first day, how were you and the engineer monitoring? Were you still summing both the mic'd signal and the...

So I tried a few other tubes in it with no luck sadly; same crackling and lack of volume. Curious if anyone else has had non-tube related crackling sounds and volume issues with More. Hard to appreciate what you have until it's gone, and I'm definitely missing it now.

Anyone have experience with tubes dying? Having an issue with More. Was playing through my beloved More last night; over the last week it has developed some intermittent crackling, which I initially attributed to some RF from my cellphone. Sadly it seems it was actually a failure of some sort...

Thanks for linking that discussion - the key difference here is that the Ampeg PF amps already have a built in load with no need for modification and have a dedicated power transformer DI output. That's all highly attractive as I'm looking for the whole amp compression/distortion but at louder...

I don't see this talked about much - does anyone use the transformer out to push a small Class D amp with a much higher power rating? My hope is this would give me the output tube/transformer saturation I'm hoping for but at a weight and portability much greater than a V4b. I'm really just...

That's a strong statement... got a chance to play it with my band the other day, it was an absolute hit; now you're telling me it gets better??

I had a Guyatone BB-1 that has since been traded away. Using it as an overdrive, it's just awful; perhaps I had a dead unit, but it's incredibly thin sounding. The EQ section was nice though, parametric mids with a bass "color" knob; using that with the gain all the way down was an interesting...
