Yellow Jackets® converters are a type of specialized adapter which permit the use of EL84/6BQ5 power tubes in place of 6V6, 6L6, EL34, and 7591 type vacuum tubes.

Yellow Jackets® converters allow you to harness the musicality of EL84 vacuum tubes in amps that don't use them already - it's like getting a whole new amplifier!

Yellow Jackets converters give you simple Class-A operation from any amp.

Anyone know more on this?

One of my guitarists tried them in his Fender Hot Rod Deluxe to get more of the English sound. They worked well....did get a bit hotter....I thought it made everything a bit too glassy. They are a quality product so if its what you want for your amp the build and design shouldnt be an issue.

He eventually sold that amp and got a Bogner Metropolis which I couldnt recommend more. This is the real stuff.

Yeah....kinda...It wasnt right for that amp IMHO...Kinda choked the Fender right out of it. It sounded like the speakers were working hard to get out the tone. I still think it was the amp and not the converters.

That Bogner.....thats my second favorite amp in this class. First being a Conrad.....VHT Pittbull45 is third.

AD. You also couldnt use the channel switching with them.....I never found out why.

Rivera isn't - I love the amps and dearly want them to be the top dollar but they unfortunately hit about 85% for me, with hard work and extortionate expense in tubes to take them to 95%.

I haven't tried the Conrad, but I have just had a Retro-King RK45 built for me - I don't know if you remember I was planning on getting a Marshall Plexi rackmounted to go with my Twin rackmount, but I ended up getting this after speaking to every custom builder out there and it does both jobs.

Its basically a replica of the Plexi Hendrix used with the capacitor mods, but runs at 45 watts with 6L6 tubes instead. I've had one channel wired to sound Twin-ish and the other is a very Plexi distortion - the cap mod is switchable, the two channels are discrete and I have some other goodies like a post-PI master volume, switchable true-bypass effects loop and negative feedback variax built in.

Reason I mention it Chris is that all my guitar rig stuff is covered in the same vintage cream tolex and this was mis-covered in white, so I had a second cabinet made. So I actually have a spare white cabinet for an RK45 which means if you did decide to try/buy you might be able to get just the chassis made and have my cab.

I'll post some pics and sound clips once I get my photographer through the studio.
