The Soldano Astroverb 16. Regardless of your style and application we have you covered!
All of our Soldano Astroverb 16 full Retube Kits are designed specifically for these amps. Every kit is configured to provide a specific sound/experience.
The default power tubes for all of our Soldano Astroverb 16 kits are the JJ EL84’s. However you can use the Power Tube drop down to select the JJ EL844’s. The JJ EL84’s will on average maintain the OEM headroom/breakpoint for the output stage. The JJ EL844’s will drop the output power around 25% lowering the power tube breakup point.
These amps are adjustable bias. All you need to check and set the bias is one of our 9 pin bias probes with a Multimeter, or our all-in-one 9 pin “Pro One” bias probe (which reads plate voltage and plate current simultaneously). EL84’s should bias up to between 22 to 26 mA per tube. The JJ EL844’s are a 9 watt tube and should bias up to between 16 to 20 mA per tube.
The Standard Retube Kit is as close to OEM as possible. Maintaining the amps stock level of headroom and gain while providing a warm but even handed overall sound. The kit includes one matched pair of JJ EL84’s by default, one Balanced JJ ECC83S for the phase inverter (V5, farthest from the input jack), and four Standard JJ ECC83S’s for V1 – V2 – V3 – V4.
The Gold Pin Retube Kit uses the JJ ECC83S Gold Pin variants to provide a smoother, creamier, and more singing overall sound. This option is less aggressive and has less “teeth” when driven hard. If you like a classic raunchy gritty overdriven tone, we recommend looking elsewhere… If sweet, open, and more refined is what you’re after this kit will do it. The kit includes one matched pair of JJ EL84’s by default, one Balanced JJ ECC83S Gold Pin for the phase inverter (V5, farthest from the input jack), and four Standard JJ Gold Pin ECC83S’s for V1 – V2 – V3 – V4.
The High Gain Retube Kit uses our hand picked high gain selected JJ ECC83S’s. If you’re looking for maximum crunch and grind this is where you want to be. Sonically this setup is very similar to our Standard Retube Kit but with a little extra gain on tap. The kit includes one matched pair of JJ EL84’s by default, one High Gain Balanced JJ ECC83S for the phase inverter (V5, farthest from the input jack), one Standard JJ ECC83S for V4 and three and three Handpicked High Gain JJ ECC83S’s for V1 – V2 – V3.
The SRV Retube Kit uses the JJ 5751 in the V1 position. The JJ 5751 is a purpose built low gain 12AX7/ECC83 substitute. Stevie famously used these to eek out a little extra clean headroom, and you can too. Expect about a 25% reduction in gain, which is like having an extra click on the dial before breakup sets in. Great for clean players and pedal users. The kit includes one matched pair of JJ EL84’s by default, one Balanced JJ ECC83S for the phase inverter (V5, farthest from the input jack), three Standard JJ ECC83S’s for V2 – V3 and one Standard JJ 5751 for V1 (closest to input jack).
The Gold Pin SRV Retube Kit uses the Gold Pin tubes for a smoother richer tone. The kit includes one matched pair of JJ EL84’s by default, one Balanced Gold Pin JJ ECC83S for the phase inverter (V5, farthest from the input jack), three Standard Gold Pin JJ ECC83S’s for V2 – V3 and one Standard Gold Pin JJ 5751 for V1 (closest to input jack).
The ECC803 V1 Retube Kit uses the Long Plate JJ ECC803S in the V1 position. The JJ ECC803S’s are a little lower in gain than the ECC83S and have a very fat mid and a little hotter high end which gives a very vintage tone with lots of chime. The kit includes one matched pair of JJ EL84’s by default, one Balanced JJ ECC83S for the phase inverter (V5, farthest from the input jack), three Standard JJ ECC83S’s for V2 – V3 and one Standard Long Plate JJ ECC803S for V1 (closest to input jack).
The Gold Pin ECC803S V1 Retube Kit uses the Gold Pin tubes for a smoother richer tone. The kit includes one matched pair of JJ EL84’s by default, one Balanced Gold Pin JJ ECC83S for the phase inverter (V5, farthest from the input jack), three Standard Gold Pin JJ ECC83S’s for V2 – V3 and one Standard Long Plate Gold Pin JJ ECC803S for V1 (closest to input jack).
