We still offer repair services on anything we have ever sold!

This was a pair of Paraglows I received for repair that got the special treatment by the shipping company.  The most sensible course of action turned out to be having new top plates cut out of thicker material in a physically larger size.  These were powder coated in textured black powder and the extra space allowed me to spread out the build components a little bit. 

All capacitors and most of the resistors were replaced during the rebuild.  I will do my best to maintain an inventory of these new chassis plates as undoubtedly there are other Paraglows out there that have suffered a bit while traveling.

Since this project is technically built from Paramount parts, I suppose it belongs here. 

I was approached and asked if it would be possible to build a parallel feed 2A3 monoblock where the output transformer could be changed out easily.  This morphed into monoblocks with polypropylene power supply/cathode bypass caps, then naturally shunt regulated 2A3 amps.  Leftover Paramount parts were used, and the TFA-2004JR transformers can be unplugged and unscrewed from the top side of the chassis (with the amp off of course) to facilitate iron rolling. 

The chassis height was increased to accommodate some enormous Clarity Cap  parallel feed capacitors, and they were even given their own wood stretchers to attach to!

This is one of a pair of Paramour I amplifiers that came to me with blown Hammond power transformers.  Although our replacement PT-2 power transformer is no longer in production, our PT-10 power transformer has the perfect high voltage winding and a low voltage winding that is happy heating a 2A3 provided a DC supply is used.  Along with new power transformers, I replaced all the power supply capacitors.

Having only been onboard since the introduction of the Reduction, I really like seeing the photos of older BH products.

I took this pair of Paraglows in for repair/rebuild recently.  I like seeing our older amps in this condition, as it means the owner has been using them nearly daily for the better part of 20 years.  This pair had tons of bulging capacitors and cooked resistors, so a complete rebuild was in order.

Here they are all redone with everything spread out.

Wow, nice work...John

It is fun to see your wok Paul! Some great rebuilds! I am familiar with your rebuilds as you have done a couple for me! The SR2A3's are amazing!!! Thanks

Enjoy seeing the befores and afters.

Me too! It's one of the most interesting thread of the forum, so full of ideas...
Please, keep on posting Paul!

 Paul,

   I have a small project that will likely not be completed soon enough, so I am asking you assistance. It is a basic Quickie kit, a PJCCS, and a FIX all combined within one chassis. I have gotten as far as making the Q work, yet, the PJCCS needs your help, as well as the Fix in the final product. Here is a shot in case you are interested.
 My attention has been side lined for a SS amp project, so this needs attention in the meantime.

I often find that one of the tougher things to do is to work on partially completed custom pieces.  How much space is there inside your preamp?

Paul,

 I completely agree. Let me get some photos together for you. What helps is that the chassis can be disassembled to the point where it is pretty accessible. The Fix portion is a bit tight being in there though, so it might end up unused.
